>> this is al jazeera america, i'm not thomas drayton in new york. let's get you caught up on the top stories this hour. >> climate change is a defining issue of our time. there's no time to lose. >> the head of the united nations joins protesters in new york city for what organizers say was the largest climate change march in historiry. leaders gather for the 69th session of the united nations general si sem bli. tonight in the week ahead we look at the u.n.'s changing

mission. after days of fighting in yemen, houthi fighters sign a peace deal. in sierra leone, a 3-day nationwide lock down to help the spread of the ebola virus is over. thanks for being with us. we start tonight with a climate change rally led by thousands around the world. more than 400,000 protesters, according to organizers, took part in what has been billed the people's march, touting it the biggest event of its kind. >> reporter: this is more than a march for climate action. organizers say it's a movement, led by those on the front lines of climate change. coastal communities who are losing their neighbourhoods to rising sea levels and weather,

to indigenous groups who travelled from the south-west of the united states. >> the delegation is impacted by fossil fuelled development. there's a big boom going on, history of uranium mining, and the area i work. we felt the negative impact of all these, and we are here to join with brothers and sisters to push forward. >> plenty of dignitaries on hand, including former vice president and climate activist al gore. united nations secretary ban ki-moon as well. ban has convened a summit here in new york on tuesday. there are efforts under way to reach a binding international agreement by next year. >> nothing will happen this week in the u.n. the big action is on the streets. this is finally the climate change movement coming of age, demonstrating that it is a profound concern for people.

it is the biggest political gathering about anything in the united states in years. that's the message we need to get across. environmental activists have been down this road before. what is different is the broad coalition. state-based groups, to labour unions - they are hoping to create a ground swell of support for action. major unions brought thousands of people reflecting labour's evolving position on how climate action will impact jobs. >> it's not going to impact the economy, it's the only choice we have. if we don't combat climate change, our economy will be devastated. >> with strengths in numbers, economists are calling for an agreement to keep the rise under 2 degrees celcius, by phasing out carbon pollution and switching to clean energy by 2015. they say we must act now, or pay

the price later. >> well, new york city's march may have been the largest, it was not the only demonstration. in london, 40,000 marched past big ben carrying signs calling for a cleaner planet, and then they called on money to be allocated in the budget. many said the cause was not political. they wanted to raise awareness to help people control the consumption of energy. 10,000 turned out, marching past the bran don burg gait. they called on angela merkel to take more action. >> i spoke with jake smith of the natural resources defense counsel. he attended a climate march and said that he was shocked by the

turn out. >> i don't think we expected that large a turn out. i was over whelmed. it was reams of people. we stood in line for two hours. the group in front of us had moved, there was so many in the street. >> what message does this send. >> i think it sends a powerful message to world leaders that the people have their back. we hear from politicians, the kinds of actions we need to do. it's a massive turn out on the streets of new york. it's the worse time to be in new york, traffic shuts down. it's bad. there's a large number of people saying we need action. >> something has to be done. i want to look at troubling statistics. carbon pollution was higher. 40 billion of carbon dioxide was pumped into the world by burning coal, oil and gas.

it's a 2.2% increase. china, united states and india were the top polluters. what would your organization like to see coming from the summit. >> it's important that the polluters deal with issues. they are suffering, it's driven by the overconsumption of coal, and it's time for china to realise that it needs to deal with that. at the same time the united states needs to deal with carbon pollution. president obama has begun to put in place a plan to reduce emissions from the power sector, the biggest source of carbon pollution, there's a number of other steps that it needs to do. what we are looking for is the countries to step up to the plate and signal the deeper cuts. >> do you think we'll see real policy change? >> i think the signs are powerful. we need a movement that is powerful to send the signal to the politicians, that it's time to wake up and deal with the

change. whether or not humanity can deal with the challenge, we have the power in our hands. wind, solar, energy is a solution. we can deal with the problem, reduce energy and create jobs across the world. >> while the u.n. meets, indigenous leaders from around the world will be there, taking part in the first world conference on indigenous people. along the concerns, keeping the natural resources intact. one woman travelled from the amazon to make her voice heard. >> it was a journey of 3,000 miles, from a village deep in the rainforest. an indigenous woman, here to ask for one not so simple thing, to leave much of ecuador's estimated 8 billion oil reserves in the ground. >> our people believe that

petroleum is the blood of our ancestors deep in the earth. the earth is the mother. you are taking the blood from the mother and creating an imbalance. >> it is home to 1,200 people, and for a decades long battle in the international courts, stopped ecuador's government from opening it up to big oil companies. they want to bring that model to the rest of the world, and put themselves on the front lines of the battle against climate change. >> we have a proposal based on scientists reports that say 50% of the known petroleum reserves need to stay under ground to avoid raising the earth's temperature more. what are we waiting for? you can begin with us. we have been resisting for years. we don't want petroleum exploration or more contamination of our lands. >> they shared the community

struggle and victory with other leaders from around the world. from the south dakota to the navaho of the south-west to native hawaiians, each brought gifts and shared stories of fighting for the earth. leaders brought water from the communities, and combined it during a water ceremony. water was blessed and drunk by all, and poured back into the hudson river. >> here on the banks, the message was taken all the way to the united nations, and demand action on climate change. >> the chief will represent her tribe at the u.n. >> the more of the indigenous people who can be seen, maybe we'll be heard, we don't know. but the states will open up their eyes and their ears and start listening and hearing. >> it's a message indigenous people say they have spent

generations trying to get across. change that they believe must begin with them. >> because we have time tested, experience and a relationship with mother earth. it's hoping that the other world will catch on to that. >> reporter: catching on before it's too late to combat climate change. earlier this evening i spoke to ellen gabriel, mohawk indian, and will attend the world conference on indigenous people. other communities chose to boycott the summit. we are told why. >> first of all, it's not a real-world conference. that would have three days. this... >> this has a day and a half. >> yes, about a day and a half. from the beginning there's not been full and effective participation of indigenous people in how to implement. there's a lot of discussion on how we can consult with indigenous people. there's language that is so week that from the get go people have

said "we don't want to be part of it", but if we are not there to hold the line and make sure the states don't weaken the destination, we would be remiss to not be here, because a declaration, i think, is an important human rights instrument for indigenous people. there's states like canada that already have, like, reservations about personalitying consent. especially when it -- parenting consent. today we had a march on justice, and we talk about the exploitation and appropriation and theft of lands around the globe, and abuse of rights. this u.n. document is a lot of fluffy, flowery language that is not going to promote and protect the people's rights. >> where do you stand in trying to get your voice heard, and what do you see coming out of the conference? >> this document is done.

we are there to sit and watch. it will be frustrating. we need to look at the next steps - how the u.n. can help in implementing the u.n. declaration, and how do we get it in the domestic legislation of every state that is a member of the u.n., with full and effective, and protection of our lands, resources and water. many said indigenous people are on the front line of protecting the land and the environment. we don't want words, we want action, and this conference falls short of it. >> in addition to climate change, also on the agenda at the u.n. secretary general assembly - i.s.i.l. of the u.s. says it's forming an international coalition to take on the threat. randall pinkston reports the involvement of one country is raising eyebrows in leaving the obama administration to clarify stations. >> sam they power made the --

samantha power made the rounds of the talk show and talked about the president obama plan for i.s.i.l. she clarified announcements about iran's role in the fight. first, secretary of state john kerry on friday at the u.n. security council, where he spelt out the coalition that the u.s. is trying to form. then ambassador powers addendum on sunday. >> it must be extensive and include close collaboration across multiple lines of effort. it's about taking out an entire network, decimating, discrediting a militant cult masquerading as a religious movement. the fact is there is a role for narrowly every country in the world to play, including iran. >> let me stress that we are not coordinating military operations or sharing intelligence with iran, what the secretary meant

is that he too says i.s.i.l. is an enemy. >> iraq's before has been destructive, pointing out that it supports bashar al-assad, a regime opposed by the obama administration. >> randall pinkston in washington. secretary of state john kerry met with iran's foreign minister at the walled observe hist orria hotel. the meeting lasted for an hour, and they discussed i.s.i.l. kerry expressed interests in restarting negotiations leading to an easing of sanctions in iran. both are here for the general assembly. more coming up on "the week ahead", coming up in a few minutes. heavy fighting in northern syria drove many residents over the border to turkey. more than 70,000 syrian refugees crossed the border, most ethnic

kurds. they fled when fighters from islamic state of iraq and levant captured several villages. turkey closed a key border crossing saying they wanted to protect kurdish fighters were entering syria. >> the government will not give details of the deal. 49 turks were held hostage. recep tayyip erdogan met with the families, telling them there were things we cannot talk about. the hostages were seized in iraq in june, and returned to turkey on saturday. ahead, details emerging about the man accused of getting into the white house with a knife. the latest on the manhunt for the man would shot two state troopers. a threat to the lives of people in pakistan.

we are learning more about the man accused of getting into the white house with a knife on

friday. he's a veteran, omar gonzalez, decorated for service in iraq before retiring in 2012. he is expected to appear in full court and broke that the white house minutes after president obama left. a former secret service agent says it's possibility the break occurred because everyone was focused on the president's departure. pennsylvania police are making progress in tracking down eric frein, the man accused of ambushing two state troopers. photos of ak-47s, and ammunition was found, and they belief it belonged to eric frein. they say he may have planned the shootings for months or years. it's believed he's in a wooded area close to where he lived with his parents. >> up until now the advantage has been that this is his backyard. he knows the rugged terrain. tactics cooperation people know his backyard, the area he felt

safe in. we are pushing him hard. he is no longer safe. i'm confident he'll be apprehended. >> the am bush-style shooting happened outside the blooming grof police station, 60 miles from allentown. one trooper was shot, the other recovering following surgeries. the parents of michael brown, shot and killed by ferguson police officers, rallied in atlanta. michael brown senior and lesley called for the justice department to take over the investigation. at a community rally michael brown's mother vowed to keep speaking up for her son. >> he was an average teenager. he didn't deserve that. he meant something to me. >> amen. [ clapping ] >> i won't stop until i get justice for my son. >> on thursday brown's parent

will travel to washington d.c. to rally for their son. a storm is churning off the west coast. tropical storm polo was reported off the coast. it was hit by odile, cutting power and water supplies. polo is expected to lose strength but dangerous currents will linger for a few days. for the latest on the forecast rebecca stevenson joins us. >> it hasn't lost strength. it's 40 miles per hour, but in 24 hours, like you said, i think it will die off. it's heading to the west and will be falling apart. we have seen a lot of thunder storms circulating around the center die off. there hasn't been as many. it's becoming a confirmed forecast that this is going to move out of the picture. the moisture that is within this storm, and the moisture that was from the old hurricane odile is

impacting the south-west, bringing flooding, rain fall throughout the night and we have seen incredibly heavy amounts of rain - 2-4 inches in short periods of time. what is most notable about this particular set up is that many of the service office forecasters is looking at the amount of moisture on the air, it's anywhere from 1.5 to 2 inches, it's near the highest percentage they have seen in late september. incredible amount of rainfall brought out by lifting up the air, and all the moisture. it will come down fast. the totals here impressive. salt lake city, you had a rough afternoon. through the day, down highway 89 there were incredibly heavy storms, quarter of an inch, half an inch, and four tenths of an inch for salt lake city. it was difficult driving through

the south-west. we had hail, flash flooding for south-east new mexico and texas. that's the moisture for the hurricane odile. otherwise the story is temperatures of we are cooling down with cooler air sweeping through the great lakes and temperatures have dropped by 18 degrees around the great lakes. >> it's fall after all. >> yes, it is. >> let's take you around the world. in pakistan doctors are warning a health crisis is unfolding. stomach problems and skin diseases are problems. nicole johnson reports from southern punjab. >> reporter: a baby girl four days ago, named after her mother. sama had to give birth on the banks of the flooded fill. the family's home was swept away by the rising tide a week ago. >> i was in acute pain laying on

the bed for two days. i can't afford to visit a doctor or get medicine. the week are suffering, especially children, pregnant women and the elderly, we count a dozen babies in the small camp alone. children are developing stores. >> we need a doctor and funny, care for the babies, hygiene, food and clothes, and a tent for giving birth. a government has given us nothing. we are exhausted. >> reporter: 2.5 million have been affected. in one of the worst floods that pakistan has seen. many can't go back to the village, and are living in camps with no toilets and clean water. >> across huge areas, floodwaters are starting to recede. it's leaving behind stagnant water. it brings disease and miss ery -- mystery.

people are using the water to bathe, wash clothes and dishes and they drink it. some are getting sick. >> they are living next to the homes, not inside, because there's water there.

when we come back after break, "the week ahead," the of

9th assembly of the united nations convenes in new york. key players and issues. stay with us. sh

welcome back to al jazeera america, here are the top stories - organizers say more than 400,000 participate in what they call the people's climate march, the biggest even of its kind, and one of many similar marches around the world. after days of violence in yemen, houthi fighters and the yemeni government signed a peace deal, including a ceasefire and forming a new government more inclusive of the houthi leaders say they will not withdraw from areas in the capital that they control. we are learning more about the man accused of getting into the white house on friday. he is was a veteran, omar gonzalez, decorated for service in iraq in 2012. he's expected to appear in fraurt tomorrow.

it's sunday night time for "the week ahead". world leaders are gathering for the 69th session of the united nations general assembly. they have plenty to talk about - from the refugee crisis in syria, ebola in africa, and the threat of i.s.i.l. u.n.'s mission is to keep the peace and help those in need. the track regard is uneven. we begin with courtney kealy >> reporter: the u.n. high commissioner for refugees pleads for international aid. >> we are approaching in turkey 1.6 million refugees, and over 100,000 influx. we don't know when the numbers will end. we don't know what the future holds. it's an appeal the u.n. founders understood. helping to displace people, and palestinian refugees displaced by the arab-israeli war were earlier tasks. this may have puzzled them. >> this unprecedented situation

requires unprecedented steps. >> reporter: the security council voting unanimously to target ebola, calling it a threat to international peace and security. the united nations was supposed to be a global cop, saving future generations from the scourge of war. cold war tensions prevented it playing that role. as the european countries gave up their empire, and the organizations membership grew from a few dozen countries to 193 member states, new missions emerged. the u.n. grew, driving humanitarian relief and development in many parts of the world. according to the united nations department of public information, today's u.n. provides food to 90 million people in 80 countries, vaccinates 59% of the world's children, saving 3 million lives a year, assists over 38.7 million refugees, and people fleeing war, famine and

persecution. has 120,000 peacekeepers in 16 operations on four continents. it never became a global cop, but emerged as a successful peacekeeper from golan heights, and the borders between south and north korea. there has been glaring failures - peacekeepers in rwanda unprepared when the houthi majority slaughtered 800,000 members of the country assists tutsi minority. in bosnia serbs massacred thousands of men and boys sheltering in srebrenica, a u.n. safe haven. sanctions over seen were mired in core understandings, and the headquarters in new york often has been criticized as an ineffective talking shop, mired in bureaucracy and focussed on perks and protocol. as the world leaders converge

for annual speeches to the general assembly, defenders would say the united nations rae mains important in this central institution. as courtney mentioned the speeches start on wednesday, in what is known as the general debate. more than 140 world leaders take to the podium to address the chamber. for the u.n., it's the highlight of the year, and it's fair to ask how much attention anyone outside the world body pays to the speeches. speakers focus on key issues, including the rise to i.s.i.l., and threats impressed. they are expected to discuss the ebola outbreak, and syria's ongoing refugee crisis. looking ahead members believe the u.n. needs to broaden its mandate, focussing on international law, for example. a set of questions remain. is there too much bureaucracy. do smaller countries have a

voice? earlier i put the questions to kahn ross, founder and executive director of independent diplomat and former british diplomat at the united nations. and michael schroder from washington d.c., director of the global governance politics and security programme at american university. i asked how they'd define the u.n. mission today. >> what i look at is peace and security. and stopping wars. of course, the u.n.'s record in that is imperfect. i think the truism is as true today as it ever was, that the u.n. is only affected when the members states agree to do something about a problem. if you look at syria or ukraine or iraq, there's disunity in the security council, which is responsible for peace and security, which means the courtney upshaw is affected. when it is united, when the permanent five veto wielding members agree, it is more effective.

>> when you look at the pillars, security, global development and human rights, where is the growth the sharpest? >> a lot is crisis driven. we are starting to see a huge campaign that the secretary-general and the world health are mobilizing. in the last 10 years or so we are seeing an increase in peacekeepers dropping off in the late 1990s. we are back to almost 100,000, which surpassed the early 1990s, which had record numbers. in both those areas, but we are seeing huge sums of money continue to be put into development and humanitarian relief and refugees and so forth. probably the resources pail in comparison to the size of the tasks that they have been asked to do. >> the u.n. faces a lot of criticism, is the u.n. viewed as

a forum that as a united force? >> it's a forum. i don't think the fact that it is a forum should be dismissed. i felt when i was a diplomat that at least countries talked to each other. from the outside it looks like a talking shop, and your reporter says who pays attention to what is going on at the general assembly. it is bore of course, and the speeches are dull, but real hard-core diplomacy goes on in the corridors and suites of the united nations this week. world leaders meet. they talk about real stuff. on tuesday there'll be a summit on climate change, which in some ways will be a precursor to what will be a major treaty to limit carbon emissions in paris, that matters. it's a serious business done there. >> i want to get back on security. how would you assess the u.n.,

it's evolution on handling security? >> that's a great question. evolution obviously had an incredibly uneven record, as your station point out. certainly the low points came during the rwandan crisis where it failed to respond to a genocide taking place while there's forces on the ground, for bashar al-assad to remove the forces and try to expand them, so they could take action and protect civilians. following that, there was a period of reflection. then some modest successes with east timor, following the violence there of getting an australian mission in with the consent of an indonesian government and starting the rebuilding process following the election. it had a better record. it faces incredible challenges. south sudan in particular, there are 100,000 people inside the u.n. bases in south sudan, that

the u.n. has become a convict prctor, and the -- protector, and the security council changed the mandate of the south sudan peacekeeping mission so that protection was a priority. i'm hoping that that is a sign that it's learning some of those lessons from the past. >> great lessons, we are talking about a coalition of 93 nations. if they work together militarily, they will wield incredible powers. what powers does the u.n. have? >> when the security council christopher gibson agrees to do something under chapter seven, decisions have the power of international law, which is obligatory upon all symmetries of the u.n. charter. there's a high form of international law, and that could be to order a country to withdraw troops from countries invaded and place sanctions on a country for a breach of security. this is real power, it has the power to mandate military

action, for instance, in 1991. it was a mandate for the u.s. and its coalition allies to remove iraq christopher gibson from kuwait. recently is passed a mandate for the use of force. it has real powers. peacekeeping is real troops in difficult places. we don't tend to do much about it. it's in the places where it hit the headlines as mr schroder mentioned or d.r.c., difficult, chaotic situations where the u.n. does good. it's imperfect, it protects lives in these places. it has power. the power isn't even. you have larger powers, such as russia, when you adopt a resolution. they have a veto power. does it show a weakness in the u.n. >> it's grotesquely unfair, the p 5 have a grotesque amount of

power, more than anyone else in the u.n. it's really, really uneven, as a former p 5 diplomat, i saw it for myself, it's the p5 that matter when real decisions are taken, and that distorts the u.n., the security council, the general assembly, and the appointment of senior officials, including the secretary-general, who is basically a creature of the permanent five. that is wrong. we meet an merritta accuratic system with someone that speaks truth to power, including the p 5. >> world leaders have a lot on their plates, our u.n. correspondent james bays has more on that. >> reporter: many world leaders are here in new york. this week they'll have to discuss a number of the world's crises. there is now, it seems, an unprecedented series of problems for them to discuss to this week. at the top of the agenda the

situation in iraq in syria, i.s.i.l. controlling situateds of land. that will be the focus of a security council meeting on wednesday, to be chaired by president obama, all the seats around the council will be taken by heads of state and government, with the exception of russia, because vladimir putin is staying away from new york. that may be something to do with the fact that another of the thinks discussed is the matter in ukraine, with the ukranian president likely again to accuse the russians of interfering in his country when he makes his speech. also there'll be discussions with the summit taking place. the situation in west africa - the ebola epidemic. they will be discussing complex. brandon carr, mali, and the democratic republic of congo. add to that, the violence that goes on in libya, in yemen, the tension in pakistan, the

electoral deal in afghanistan, there's so much for world leaders to discuss. it's likely that some countries where people are suffering will not get the attention they deserve. does the u.n. need to broaden the mandate focussing on the international law. i'm not sure that it has to broaden its mandate, it can, through a general assembly committee, work on issues of law and codify standard practices into law. the security council itself - the decisions itself, as i think were pointed out earlier, are binding when they took place after chapter seven. at this point in time the u.n. has to figure out how to sharpen the tools of international diplomacy, and the operational tools to provide humanitarian relief and prove its ability to rebuild countries and improve peacekeeping when there's violence taking place and when they are trying to implement

ceasefires. >> your thoughts. >> mr schroder is right. i don't think doing more international law is what is needed. i'd like to see greater clarity in putting the facts in front of member states when situations go wrong. a braver approach from the secretary-general in saying what is really going on, and demanding action. the secretary-general is pushed around by the permanent 5 to a great extent. to the extent informs that was distorted was put to the security council, reflecting prejudices, leading to lives lost in rwanda. there are hard lessons for the u.n. to learn. speak truth to power includes people that matter. 80% of agenda its include non-state parties, groups, guerillas, movements, political

parties who are not government and not represented at the united nations. they are left out, but need to be brought in to be consulted so the u.n. can make better decisions. >> how does the o.s.c.e. stack up to the u.n., they are close partners? >> the o.s.c.e. is a regional organization, and under the charter there are provisions for them to play an active role in diplomacy. the o.s.c.e. itself tends to have - has historically been - it was part of the cold war and the end of the cold war, an important institution in unwinding and improving relations between the soviet bloc and the western allies, there's some democracy promotion, in particular doing a lot of work in syria, or led a lot of monitoring down there. i think the u.n. continues to work on regional partnerships in figuring out the division of labour, and when they are sent

into the field, that's been a big change over the last decade - how to build the national cooperative arrangements. whether it's with the o.s.c.e., the au in africa, or with the oas in latin mebbing or the americas. >> the humanitarian stuff is an area where there's a degree of unanimity, that the u.n. does a good job. one can distinguish between different agencies, some are better led than others. one point that is worth underlining is unfortunately, because of the political power of the permanent five and the powerful states of the u.n., we don't always get the best people running the agencies, there's a baggins turn, powerful countries lobby for their candidates who are retired politicians and diplomats to get important jobs, and that means that sometimes we don't get the best people running the agencies, i think it

needs to change. collectively and with the appointment of the next secretary-general, we are demanding a better system. >> do smaller countries have a voice? >> i think the gem bli they take -- general assembly they sake seriousness, the ability to work in front of most of the countries of the world and lay out their priorities. they have a voice if that sense. in terms of taking decisions on the security council, it's been pretty well-established that the permanent 5 consult amongst themselves, if there's room for consensus, they push it through. that being said, smaller countries have been able to draft resolutions - the power of the pen, and potentially embarrass some of the major powers into having to take a stand, each if it's behind closed doors that those things have leaked out. they have a voice, and some are good at at least making sure that that voice is heard better

than others. there's clever diplomats. some of the countries have diplomats that have been there for a long time. if they are nonpermanent members, they take on other initiatives, leichtenstern has pushed hard to get a voluntary agreement on the use of the veto by the permanent five in cases of mass atrocities. i'm not sure that that is going anywhere. it has put itself on the agenda. it has made its voices heard in that sense. >> looking ahead. what role do you see the u.n. playing. can is overhaul current problems? >> i think good leadership and input from the major states, countries like the u.s., russians, it can be a force for good, stability, cooperation in the world, but i think the questions are, in fact, moot. there's nothing predetermined about them. we have a problem with global institutions like the u.n., and the i.m.f., the west bank, and

the whole post world war ii institutions that are supposed to manage the world. they are state based. the problems we confront, including terrorism, climate change, financial volatility. these are problems, problems of globalisation, and internet, inter-governmental organizations have not proven very good at managing the problems. climate change is not fixed by the u.n. terrorism, i.s.i.s., the transborder phenomenon of international terrorism is not solved by the international institutions. that is a greater security threat today. the institutions need to look hard at the way they operate, and make sure that they are talking to the right people who are involved in the issues, often they are not governments. >> your final thoughts in the week ahead. >> i think there are good

points. in particular the idea that global governance has not been able to manage big decisions. we need action. the united nations has to some extend opened up to civil society. we saw a flourish of human rites agreement, where there were actors from countries, working with like-minded governments to push through. there were important treaties, it was on landmines and international court. you haven't seen as much of that. there's some stuff going on. arms control and small arms. i think you need to see the u.n. find a way to better engage with the troops, implement a treaty, and do better jobs. building greater connections to stakeholders. >> thank you for joining us on the week ahead. >> thank you.

>> let's look at other end in the week ahead - on tuesday, the son-in-law is facing sentencing for plotting to kill americans and recruiting for al qaeda. he was convicted in march, the highest ranking al qaeda member to face a u.s. court. wednesday - the jewish new year. the beginning of the year 5775 according to the jewish calendar. friday, the government releases revised estimates of economic growth. still to come residents of sierra leone were ordered to stay in the homes for three days to stop the spread of ebola. now they are waiting to find out if the lockdown is successful. an odd scene on the subway in mexico city. we'll explain when we come right back.

on tech know, >> i landed head first at 120 mph >> a shocking new way to treat brain injuries >> transcranial direct stimulation... don't try this at home... >> but some people are... >> it's not too much that we'ed fry any important brain parts... >> before you flip the switch, get the facts... >> to say that passing a low level of current is automatically safe, is not true >> every saturday, go where technology meets humanity... >> sharks like affection >> tech know, only on al jazeera america after three days the nationwide lockdown in sierra leone is over. the extreme measure was taken to
