>> hi, there welcome to another news hour from al jazeera in doha. coming up in the next 60 minutes: >> four years of blood misery and death in syria aid agencies accuse the united nations of failing to protect civilians. >> two police officers are shot during a protest in ferguson after the police chief resigns over allegations of racism. >> sri lanka's president pledges a war crimes inquiry but

rejects international pressure to involve the u.n. >> a russian shopping center where he could by fire. many are still trapped under the rubble. >> the conflict in syria began with peaceful protest now four years later is a grinding civil war. the u.n. is tasked with protecting the most vulnerable, civilians, however, 21 leading aid agencies say the aid organization has failed to do its job. one instance of this is in aleppo. activists say the syrian regime is still dropping barrel bombs on residential communities. they kill indiscriminately. they are one of the many reasons syria has become a broken nation. al jazeera's diplomatic editor james bays reports.

>> four years ago no one could have ma'am would the scale of this tragedy. the figures are staggering, there's been no actual body count, but it's estimated as many as 300,000 syrians are dead. many have fled. 3.8 million of refugees. that figure, the main contributor to the fact there are now more displaced people in the world than at any time since the second word war when the u.n. was created almost 70 years ago. >> there's been no peace in part because there's been little unity on the global stage. there have been rare moments are agreement in the u.n. security council on chemical weapons, and the growing threat from isil, but nothing on a political solution to the dismay of u.n.'s humanitarian agencies. one of those agencies, the world food program is led by urthran

causen. >> you must get dismayed. >> i get frustrated not only when i look at the security council, when i go into syria and you see that there is no solution in sight. i talk to the government, i talk to the oppositions and they're firm in their positions and then i look at the people and i say don't they see what i see? can't they see the impact that their failure to compromise is creating in this situation? >> over the past four years the security council has left the main effort to find a political solution to a series of special envoys. former secretary general veteran diplomatic and now another seasoned official. four months ago he told the security council he had an ambitious plan for a series of what every called freezes across syria. the first one was supposed to be in aleppo.

he later even revealed he had an agreement from president assad to stop all aerial bombardment in aleppo for a six week period. since then, the plan has stalled. diplomats are now very skeptical of the chance of suction and for now, there is no plan b. syrians will continue to suffer and many more are bound to die. james bays, al jazeera, of the united nations. >> director for the center of middle east studies of middle east studies joins us from oklahoma. why has the u.n. done such a bad job of protecting civilians on the ground in syria? is it all the fault of the security council? >> well, it is, in part, because the security council's not in any agreement but it's also because the syrians are not in any agreement. there are no two sides. there is assad and a thousand

other militias. assad is determinedder to take back the country and the opposition that he will fail. if he had an arm, he could do something, but he can just plead with both sides and neither side wants to stop fighting. >> if as it seems the u.s. continues to thorn it's attitude toward the assad regime does that raise hopes of there being more unianymore tee on the supreme court council? >> in a sense the united states has become a strategic ally of assad, even though they abhor him and the way that he has slaughtered people and he's a dictator, but they need him. were he to fall tomorrow,

they're worried isis would swoop in and they would become ensconced in one of the great arab capitals and they would never get rid of them. this is why there is in a sense an alliance. we're seeing iran and iraq, as well, and the united states is working with iran and iraq. >> the war in syria's entering its fifth year. what needs to happen politically to end this carnage this suffering? >> well, that's a very good question. it doesn't look like it's going to come through any kind of outside mediation. the syrians, you know, this battle could go on for a very long time, because each of the major powers are helping their proxies enough, giving them enough money and arms that they will not lose, but not enough so they can win. that locks syria in to a civil war and there's nobody to take in, no international force peacekeeping force or

international power willing to enter syria and disarm militias so mod receipts can begin a negotiate or take on the assad regime. we have two sides that are still convinced that they can win this war. >> many thanks, indeed. sri lanka's president revealed plans to set up a domestic inquiry into crimes commit during the civil war but refusing to but a to the pressure of international investigators. towards the end of the war, it is said that this makeshift hospital was shelled patients already injured and seeking help said to have been killed by the government. now for around 26 years the tamal tilers, many women have been fighting for an independent

state. they've been accused of attacking civilians executing prisoners and recruiting child soldiers. government forces have been accused of many of the same crimes, but it's alleged that they ramped up their attacks at the end of the war. it's claimed they used heavy weapons like these to fire shells into a specially created safe zone which contained civilians. hundreds of thousands tried to flee, but the fighting raged around them and they remained trapped inside the so-called safe zone until the army defeated the tamals in 2009. the government denies committing war crimes. we have a report from column bow. >> the president promises a domestic committee which he called it starting within the next month. he said initial work has begun and that this pros would start soon. now, that committee would seek the views of the united nations.

the president has gone on record as saying that the views of the united nations and international community would go to strengthen this domestic process however pushed on whether international investigators would be allowed into the country he drew the line. he said that there has been a pros but confidential trust has been built among the international community into this domestic promise by his government and therefore no outside investigators would be necessary. he did say incorporating these views of the international community, which has very much been in touch with the government in the last few months since it came to power there teams to be some sort of good will by both sites. the previous government rejected all allegations and didn't want the process of going in or building its views. the president has talked the importance are taking onboard the international community and

its views and promise that had any domestic process would be fruitful and strengthened by all of these views being used to take it forward. >> the executive director at the center for policies alternatives said this proposed investigation could be different from prefers ones. >> i think there is prima facie evidence that there has been crimes in terms of crimes against humanitarian and war crimes and that the allegations are against both sides. forces of the government in sri lanka as well as liberation tigers. whether this credible domestic investigative unit is called is questionable whether it will deliver. people in the north in particular want an official acknowledgment of what happened

to them and they want justice. >> two police officers have been shot during a protest in ferguson missouri. they are being treated in hospital. people gathered outside the city's police headquarters after the police chief resigned following a report that found widespread racism within his department. stephanie decker reports. >> just as the protest was breaking up around midnight, the shots were heard. >> as we were about to pack our cameras up, we hear what we thought were fireworks up the street. turns out happened three more times. it was gunfire because we saw the muzzle fire from a gun on top of the street and so we all kind of just ducked down and once we dug down saw the cop was shot right next to us. >> one police officer was shot in the face, another in the shoulder. it happened at a protest outside ferguson's police department not hours following the announcement that police chief thomas jackson plans to resign. jackson long maintained that there was no race. >> on his watch but following a

damning report on his police department became the sixth official to resign in the city accused of systemic racism. his departure had long within called for by a protest movement that gained momentum after the fatal shooting of michael brown last august. the belief that the police force disproportionately targeted african-americans was vindicated last week by a department of justice report finding the local police and courts saw the african-american community as a way of making money for the municipality. millions of dollars were raised by targeting ticketing, jail and keeping poor black people in what has been called modern debtor's prisons until they were able to pay multiplies fines. the nationwide movement that has developed under the slogan "black lives matter" is about far more than ferguson and become a nationwide rally the belief that racism is engrained in american society. in madison wisconsin, there have been daily protests sips

the killing of unarmed 19-year-old tony robinson last friday. >> this highlights a universal problem with law enforcement and how its procedures have been carried out. >> protestors are demonstrating against an entire judicial and economic system that they say is racist and unfair. the resignations in ferguson will be welcomed by many. ferguson is a tiny city of 21 that you say and a change in its municipal personnel is unlikely to be enough to those wanting greater equality and change. >> we are joint live from washing to be d.c. it's the morning after the night before in ferguson. what's the latest? >> to add to a press conference in the next hour or so from the police department, what does seem to be emerging on social media, adding to super views that the local police are giving to local media is some

interesting in difference, as you saw the eyewitnesses on the ground said that the bullets came from behind them from a hill. it's basically stephanie was saying, these protests were dwindling at this point. a car park away from the police station, they say these shots hit the policeman, who are recovering, apparently. the police now though, seemed to agree at the time, they sent out a group to investigate, the witnesses say to investigate the area where the shots may have rung out from or seemed to have rung out from. now we hear the police officers use the terms whoever doing the shootings was embedded within the protestors. we're trying to see whether the police are beginning to suggest that the shooters were somehow embedded within the protestors and that will be an interesting fault line, because the protestors and other eyewitnesses maintain that no one amongst their group were

responsible for the shooting. the question now of course is how is this going to be used as this controversy over what the d.o.j. said was unconstitutional racist policing be underway currently. >> many thanks. >> four years ago australia economy was the envy of the world, but has its economic bubble burst. plus no sign of relief. mike grants arriving in greece are being given indefinite detention. in sport it's called the richest fight in history boxing's two biggest names come face-to-face ahead of their highly anticipated showdown.

>> in iraq, government forces are now fighting in the center of tikrit booked by shia militia and sunni tribesman they are trying to recapture the city from islamic state of iraq and the levant. iraq's government now controls several suburbs plus the military hospital. the battle is seen as a dress rehearsal for an assault on mosul, iraq's second largest city held by isil since last summer. >> in libya isil claims responsibility for an attack in tripoli, the latest violence in a country facing political chaos, which the united nations is currently trying to mediate. al jazeera reports from the capitol in morocco holding talks between the two rival governments. are they likely to be able to reach any sort of deal there?

>> well, there are concerns voiced by the international community. we were expecting the two delllations from tobruk and tripoli to converge on this building you can see behind me to start talks a while ago but the tobruk internationally recognized government hasn't arrived yet. they have said in the last few days that they would like to see some delay because they want further consultations with the government about the details of the political settlement, so expecting them to arrive later in the day and start talks. then the concern is again, is it going to be easy to bring both the tripoli-based government and the tobruk based government to pin down the details of a in my unity government. >> if the two sides can be brought together what are the biggest challenges facing those

talks? >> well, they have to agree on a prime minister to run libya for a certain period of time. then they will have to agree to pull out all their militias from the main cities, disband them, set up a new national army that looks after the country and that army has to be mandated and is one of the prerequisites of the international community to fight isil affiliated groups in libya particularly in the eastern part of the country. basically, you're talking about political aspects of the story. they would like to see a government to give the international community a sense that now we have peace and stability, but at the same time, they would like to see all the factions united and they would like to see isil defeated from lib yes because they are having huge concerns of isil is taking advantage of the divisions in the country further expanding in the eastern part of the country. >> many thanks.

>> to russia, where the daughter of the murdered optician politician boris nemtsov said vladimir putin is politically responsible for his death. she says that the president must bear responsibility for his shooting. the critic of putin was gunned down in moscow last month. poo tin voled the murder vile and viewed to find the killers. >> in russia, 25 people are trapped under rubble after a shopping mall caught fire. dozens have been injured in the city. >> for several hours they fought to control the flames. about 4,000 square meters of a shopping center, an area almost as big as a football pitch is burning. rescuers pulled carpets anything that can catch fire from the collapsed building. terrified shoppers watched helplessly. 600 are said to have escaped

but some of trapped inside. >> my friend was probably left behind inside, too under the rubble. >> anger grows in the official response. >> it all collapsed on them. we are standing here to clean the mother's wounds, because she has wounds to her head and leg and they are moving aimlessly about here. there is only one ambulance. >> some witnesses say the roof collapsed. others say it folded like an accordion. this shopping center is just four years old witnesses say the fire began in a cafe. eventually, the fire is controlled but with smoke still rising from the wreckage, questions are already asked about the safety of the center's electrical wiring. rob math think son, al jazeera. >> greece is trying to deal with a massive wave of migrants with 50,000 arrivals each year, many refugees. as we report now from athens,

the government wants europe to change the way in which people can apply for political asylum. >> this is comfort food for muhammed a simple bread made from flour and water dipped in broccoli stew. he shares it with flat mates. he is trying to wash away the taste of the detention center where he just spent nine months and what happened there to another tack stani detainee. >> he had been locked for 20 months, released and given a month to live free, but was arrested again. he told police he needed to work and send money home to his mother and brother and sister, but they didn't listen. three hours after they broke him in. he hanged himself. >> the second suicide in as many months here, testament to the failure of a policy of indefinite detention for people who aren't criminals. it even applies to minors.

it was greece's most recent method for dealing with the migrants. >> the council criticizes greece for detaining migrants for more than 18 months. a change in government that brought change. inmates are being released at the right of 30 a day. >> they enjoy a six month deportation waiver because they have no traveling documents enabling authorities to deport them. greece estimates 50,000 arrivals each year, many refugees. it wants europe to change the rules and allow people who need political attention to apply for asylum anywhere in europe, not just greece. >> we are 10 million indigenous people plus a million migrants. this 10-1 ratio doesn't apply in other european countries. don't they see the problem? and in the midst of a crisis, it's not a question of racism.

we just can't take it anymore. >> under the conservatives these camps were meant to act as a deterrent. that plan failed. people fleeing war and poverty are ultimately willing to face detention. legal residents is unlikely under such pressure, even under a leftwing government. he just hopes his luck will turn. al jazeera athens. >> right now in the news hour, let's get a weather forecast with the meteorologist with us once again. we are back in australia never to do things by halves as a nation has not one but three cyclones. >> just to the north, we have little another tropical cyclone. that second one is affecting people. this one that is pam a large system is very powerful, clearly defined eye on the storm and is sinking further southward. very strong winds, winds gusting to around 280 kilometers per

hour will pass to the east of caledonia, west of fiji. we are going to see heavy rain coming through here. the heavy rain leaks back into the islands over the next two days 600 millimeters of rain coming down has caused flooding here. making its way away from the peninsula gusting to 135 kilometers per hour, but we could definitely be seeing something like this to 500 millimeters of rain, maybe as much as 600 milliliters of rain in some places. it will sink further so you had wards, winds of 160 kilometers per hour, weakening but rain coming into the north reaches perth in the latter part of the weekend. over the next couple of days, it

could cause problems for the mining community. >> many thanks. speaking of the mining community, four years ago australia's economy was the envy of the world but now it seems there are clouds on the horizon and not just from the tropical storm. unemployment is above levels in the united states and europe. the australian dollar has fallen 30% from its peak. behind the change in fortunes is a collapse in the price of iron ore. al jazeera's andrew thomas reports now from port hedlund. >> he is spending time in his garden. he was a geologist in the mining industry but as prices have plummeted, jobs have been cut. >> people can'tify themselves in terms of their work, so hi, who are you what do you do? >> i'm looking at new opportunities. >> so are thousands of others. three years ago this house and

land in the mining town sold for $1.3 million. >> i wouldn't have called them crazy days, but they were long above, way above the average. >> today the house is on the market for less than half what it sold for in 2012 and hasn't found a buyer yesterday. >> as the huge industry bottom, so did this area. it has the post through which most of the economity's travel. the iron ore peaked at over $180 a ton but since clothing growth in china and a glut has brought its price tumbling down. >> the trains that rumble across the mid landscape can be three kilometers long and hold more than 32,000 tons of iron ore. four years ago that meant that the cargo in just one of these trains was worth around $6 million. today, its cargo is worth about a third of that. >> so now port hedlund is a

much quieter down. projects have been canceled. fewer people are needled to run the in are fra structure than build it. >> the port is busier than ever, six huge ships arrive and load up each day. their crews get a couple of hours onshore before starting the 15 day trip back to china. >> with prices low mining industry profits are down and so are revenues to government. when much of the world went into recession, mining helped australia avoid it, but the boom days are over. al jazeera port hedlund.

2011, and this is what it looks like now. the total number of lights visible at night has fallen 80%. look at the capital in damascus, 2011 and now, more than a third of the lights have gone out in the government stronghold. it's aleppo, the heart of industrial syria that's seen the most dramatic change. this is what it looked like before the war and this is aleppo at night now only 3% of homes there are still lit at night. for more on what used to be syria's commercial capital here's al jazeera's zeina hodor. >> it is one of the oldest cities in the world. its historic center is now in ruins. aleppo has been an urban battleground since the summer of 2012. syria's largest city has been

divided by many front lines and on many of them, sheets and drapes are used as cover from snipers. the government controls territory in the west, and the opposition controls the east. the only crossing point that allowed people to move between the two areas is now a waste land. the center was closed by the government last year. it was a dangerous journey. dozens were killed from sniper fire, but it was a lifeline especially for state and local employees relying on their salaries to survive. >> the crossing was vital. now it is a 12 hour journey. this crossing used to allow people to visit their relatives. >> society has been torn apart. in many areas in the rebel-held east, there is little sign of life. last year, tens of thousands left when populated areas were continuously hit by barrel

bombs. many others were wounded. those who have lost their life live hoods have been left to help themselves. >> we need money to go to turkey and get treatment. we have been forgotten. we want somebody to help us. >> health facilities were bombed in the start of the conflict. the people of area managed to set up makeshift hospitals to deal with the many casualties of war, but they are not up to the standards needed. >> we don't have surgeons. most of the doctors were either killed or fled. we don't of med sip for diabetic patients. >> the health system has all but collapsed. >> the syria war is entering its fifth year. neither side can claim victory. an initiative by the united nations to freeze the fighting in the city of aleppo didn't achieve much and the people on both sides of the divide remained trapped in what many

describe as a deadly stalemate. >> it's a daily struggle. it doesn't just take hours to buy bread government planes have targeted crowds standing in bakery lines. for the warring sides the battle for aleppo is strategic but has destroyed the lives of those living in what was once syria's commercial capital. zeina hodor, al jazeera beirut. >> venezuela's government has given president maduro initial approval to rule by decree. he asked parliament for the extended powers to fight what he calls u.s. imperialism. we have a report. >> president nicholas maduro was greeted tuesday with a standing ovation in venezuela's national center. he was there to ask for extended powers to fight what he calls impending imperialist threat. the move comes after the u.s. branded venezuela a national security threat.

order to present, for example the decision of president obama with sanctions against people in venezuela, against the whole country. they want to present it as a show. >> president maduro said he needs special powers to protect venezuela. government critics question whether he won't use the enable law to gain the electoral advantage he needs to maintain control of the congress. >> calling venezuela a threat to the u.s. has cost indignation among neighboring allies like ecuador and cuba. until the u.s. responds with hard evidence, it is likely president maduro row will continue to seek greater popular support. caracas, al jazeera. >> in somalia, seven people were killed when al shabab fighters detonated a car bomb outside a regional government headquarters.

50 million people worldwide expected to reach 135 million by the year 2050. scientists in australia may have found what they say is a new weapon in the fight against alzheimer's. people with the disease have what's known at tangles and plaques in their brain. these are abnormal clusters of proteins that stop brain cells from working properly, roll in memory loss. researchers took genetically modified mice and performed an ultrasound technique on them over a few weeks. it almost completely cleared the clusters in 75% of the mice. there was no apparent damage to brain tissue and their memory improved. researchers say the results are promising, but it will be years before it could be used to troat humans. they say more work needs to be done to understand the side effects and whether it will work with brains in humans. >> we need to look at different approaches to tackle an illness

like alzheimer's disease because it's an extremely difficult disease to treat. many people will be familiar with ultrasound and the context of perhaps scans for babies and other things. this is more invasive, so the technique they've used is quite invasive and not one that necessarily lends itself immediately to being used with people. we've got a very long way to go. i think there's interesting results in the mice. we've also seen before in mice and in people that when we cleared away this am lloyd protein we're looking at, it doesn't necessarily help people if it's too late in the disease pros. there are many challenges to bring a new treatment for alzheimer's disease. we certainly need them. we've got a long way to go in this case. >> building ahead of what many are calling the biggest fight in
