experience. isn't that ironic - "he was free"... i said "he was 'free' to have all that experience". my father liked it. >> this is al jazeera america, i'm michael eaves in for richelle carey. thousands march to commemorate the 50th anniversary of the selma civil rights event bloody sunday a military offensive against boko haram. banding together for equal rights - nations around the world celebrate international women's day drug source - al jazeera takes you to the poppy fields in

mexico that helps supply america's drug addiction. thousands of people gathered in selma alabama to remember the city's pivotal role in the civil rights movement. today they honoured former president lyndon johnson for signing the voting rights act in 1965. he was motivated by what happened in selma. 6,000 marched to montgomery barack obama to protest fair voting laws. they were med with bloody violence. there were tributes to the civil rights leaders. many say there's more to go. tony harris is there. you've been there all week, it was the culmination of the week.

>> you're right. the day began in a symbolic and historic place. brown chapel ame church. 50 years ago it was the organizational hub of the selma marches marches. 50 years ago the names from malcolm x, and martin luther king junior. today it was the attorney general eric holder, and king iii at the selma moment at brown chappell. >> when we think about what martin luther king would want us to do. i imagine he'd tell us that work was not done. we are a better nation and the behaviour that we are exhibiting... >> all right. so i want to play for you. i want you to hear the attorney-general. eric holder from brown chapel.

recently the attorney-general has been playing out his own personal agenda of the its he'd like to take on once the next attorney-general is confirmed by the senate. have a listen. >> we'll march on until every citizen is afforded his or her fundamental right to vote. we'll march to the bright horizon, to the day where all americans, young or old, rich or poor, no matter where they are, where they are from no who they, has equal share in the american dream. >> i want to you look behind me at the edmond ped us bridge -- edmund pettus bridge, things are settling down, the curtain is coming down on a remarkable weekend. rush hour on the bring was 2 hours ago, where you could barely breathe or move. as we wrap up this weekend, the young people have been giving their plarching orders --

marching orders, we'll see where it goes from here. it's been a remarkable weekend. >> and that is a good point. with new marching orders what will the latest generation of community activists do, now they have marching orders and now they have a clear idea of the people that came behind them to organise and affect change. >> yes. one of the speakers today essentially was saying that more was done by the people 50 years ago with less and that more needs to be done by young people today who have more. if you areling to all of the -- are listening to all the speeches from the weekend, it is clear that a lot of people see in moving forward, pushing the congress to strengthen the voting rights act. we'll follow that and a better sense because people - they take the call, they motivate rally,

organise and turn it into definitive action moving forward. >> that was a central part of president obama's speech yesterday, relative to voting, and he chastised some people who had the right to vote but don't do it for whatever reason considering what people 50 years ago did, so they can have the right to vote today. >> if that was an important moment you are good to point it out. the president was saying what is your excuse. people walked across the bridge. they were on the ground for a year organising in selma, 80% of dallas county in those days was african-american. 1% of legal voting aim was registered to vote. that was 50 years ago. more elected officials, more african-american american officials, and yet what was pointed out is that the franchise was won through sweat,

equity, blood and tears, and, yet, there aren't enough people going to the polls. his question, his rhetorical question to the crowd yesterday is why do we give up so much of our own power. it will be interesting to see if the words from this weekend translate. >> absolutely. tony harris live in selma. later we'll go back to selma for more on the weekend, including a view from the other side of the bridge. daughter of former alabama governor george wallis reflects on his complicated life and legacy. stay tuned for that a full-scale military offensive against boko haram is now under way in in north-eastern nigeria. ground troops from niger and chad began operations this morning. air strikes started last night. chief executive was on the ground in nigeria, where boko haram is based. >> what we see is a culmination

of a month of talks between nigeria and niger, and nigeria and chad. this is around the lake chad area and cameroon, badly hit by boko haram over the last few years. in the last few months it's worse. boko haram fighters have basically erased the border if some areas and go across and what we see now is a rob oft chadian military and from niger, they are trained to deal with this, going in at the same time as nigeria military is pushing. >> boko haram has been blamed for four suicide bombs killing 54 people wounding 143 and pledging allegiance to i.s.i.l. is that a response particularly

in response to what has happened recently. >> there's no real connection between boko haram and i.s.i.l. i spoke to some of the officials responsible for training boko haram: the fear is that boko haram will reach out to groups such as i.s.i.l., such is al qaeda, to operate in northern africa, for weapons, for training and ideology. what people on the ground tell me this is about the failure to defeat boko haram, when it could have been defeated or the failure to go after boko haram with enough weapons that nigeria soldiers tell me we didn't have, with political will. which officials admit there the wasn't, and with enough heavy-duty strategy weapons that the military brought in in the last few months. you see a lot asking why did it

take so long. nonetheless, the effort is still larger than it has been against boko haram. both within nigeria, as well as with the niger, chad and cameroon all of them trying to provide a buffer nick schifrin reporting. the new offensive follows a rash of deadly attacks many died hundreds injured. we have more from abuja, nigeria. fighting against boko haram. the objective is to push the fighters into a corner ahead of elections. so far more than 30 towns and villages have been liberated from the fighters, since chad

and niger joined effort to fight the group much for niger, chad and cameroon it is crucial. 5 years of violence cut off trade. there's a fear that the group, if left unchecked, will become a bigger threat to the region. boko haram will be crushed in the last 5 years, and they are in a position to do so. >> we are adequately equipped. there's a real change. we have taken delivery of changes, and from the president himself, we have taken delivery of new equipment. one is that you see here. we have not found it yet, boko haram. it is a defensive operation. we are on the offensive. >> the military had in february asked for 6 weeks to clear the north-east of boko haram.

to make way for elections. but the offensive against boko haram forced the group to resort to the old sort of bombing. over the weekend, attacks in maiduguri killed more than 50 injuring more than 100, hours after, the group's leader pledged allegiance to i.s.i.l. a move by the military as an attempt to bring i.s.i.l. into its operations. on saturday a regional force of 8,000 troops was expected to help with the effort of the multinational task force five suspects have appeared before a yug in connection with the -- judge in connection with the murder of russian boris nemtsov. one man was seen in a came hiding his face as he was charged with murder.

another claimed he was guilty. three others had a hearing behind closed doors, and prosecutors have 10 days to charge them. boris nemtsov was gunned down on a bridge, an outspoken critic of vladimir putin. >> a sixth suspect in the murder took his own life as police took him into custody. >> it happened in the chechnya region. he blew himself up with a grenade, after a standoff with arresting officers. >> a ukranian military spokesperson says one soldier has been killed in the past 24 hours. three others were injured in fighting. as john hendren reports, both sides accuse each other of ignoring the ceasefire. >> reporter: from the rebel front line in eastern ukraine, the ceasefire is noisy. this man says he's a russian special forces trainer, volunteering to fight the rebels takes it to a trench

where gun fires and borders are heard. >> get down did you hear the grenade launcher hit us. we are 800m from the front line. grenade launches are being used to fire on the people from public positions. right now we are hunkering down and waiting for the firing to stop. on the other side of the front lines, a few days earlier, ukranian forces said separatists were firing on them. >> in principle the ceasefire is holding. there's regular small arms fire. before you arrived several shells landed op our side. before you arrived they were firing on us. saturday was the deadline to remove tanks artillery and other equipment. both sides were complying. after we spotted this tank

concealed behind a building 10km from the front line. each accuses the other of violating heavy weapons ban. >> translation: the rebel army withdrew heavily artillery from the front line positions. the terrorist battalion have not wrooun any ides. they move forward military equipment and artillery. every night they are coming closer. >> with daily violations of a ceasefire, it is not clear that the end of the conflict is closer. >> it's been a year since malaysia airlines flight mh370 vanished. no trace has been found. today a report was released by malaysian authorities. it revealed when the plane went mission the battery for the boeing battery recorder had been expired for more than a year but offered no new leads on what

happened to the jet. some relatives of missing people criticized the report. it has been a whole year and until today there's no truth malaysia said the plane lost collection and the next day it was missing. we do not know it's true. if it's missing fine the body of my son. now that's nothing. you are hiding information. australian prime minister tony abbott says the hunt will continue even if the search off australia coach doesn't find anything. flight 370 was on the way from kuala lumpur to beijing when it went off the radar. it's hoped the mystery could change and improve how each plane tracks in the future. jacob ward explains. >>. >> malaysia airlines flight 370 was an unimaginable loss. the total disappearance of 239

people. 2014 was full of pad -- bad news, in july a shooting down of a plane. an alalgerie crash in mali. many dead. but when you look at the statistics. 2014 was a safe year. and the single greatest year of aviation ever. there's at least one clearing problem left. in of the vast stretches of ocean, there's no radar, and when air traffic control loses contact with the plane, it's gone. it doesn't have to be that way. 90% of long haul sites carry a satellite based position. they ping their location 30-40 minutes at most.

indonesia, malaysia created a trial. it's not real time tracking. the obvious issue is that there are situations where aircraft can be out of touch. >> might data recorders tining. officials replieded for years making them easier to detect. we have recommended that recorders be more robust. the problem is money. the f.a.a. put a billion dollars into a traffic control system that will make the system more efficient. when it comes to outfitting change that's something the airlines have to pay for. your risk is one in 11 million the question now, a year after it vanished is how much it would

cost. or if it's possible to do away with fatal crashes. >> demanding gender equality nations coming together for international women's day. that is next on al

>> gender inequality is not just a men's issue. it affects all of us.

celebration, it has shown up on social media as a call for action by the government and its citizens to improve the lives of women. many women in rural south africa live in poverty, al jazeera's erica wood met a group of women who use farming skills to help themselves and their community. >> in this dry region these women teamed up to grow vegetables on a selective farm able to grow enough to feed their families and sell what is left over. >> before we were able to buy everything now we grow everything. it's not beneficial to our families, but the other communities who come and by from us. some suggest up to 70% of all the food eent is grown by women. few own the land they farm.

they are disadvantaged by unequal laws and tribal traditions that favour men. the women are left vulnerable. >> when men take the lead in forming, they farm and take the money to buy alcohol. >> the benefits of giving women the rites to own land and the skills to work it are exonen shall. studies prove that women are more likely than men to use the income to benefit not only themselves and the children but the wider community. >> mavis won awards for her farming. the former school teacher growing the treat to combat malnutrition. it's been so successful she's exporting and mentoring other women to farm the tree. >> they'll feed the children. they are going to take the children to schools, and do anything for the whole. and mavis is benefitting the whole community. any profits she makes she puts

misunderstand named for the 2014 recipient of the nobel peace prize. i asked her what were the challenging issues that women faced. >> women are getting the quality of education that will allow them to earn an income. many do not have secondary education. it's a time when women are ready for marriage. at the age of 12 or 13 you see a drop in enrolment of girls, which means they are gettingaried having children and are trapped in a violence of

poverty. >> when it comes to equality you have to get the side that has power to understand that quality is not there, and needs to be there. especially when you deal with cultures and countries, trying to get those empowered to give women the equal rights they deserve. >> that is power. when you an access to money and investment of income. it's not just the women that prosper, it's the families communities, they take the country forward with them. one of my favourite statistics is 80 to 90% of every dollar earnt by a woman is reenvested

into the community. you see investing in women being the exponential way. focussing on the data is important. holding government's policy leaders accountable not just to make the policies but to make sure they are delivered pop. and culture shifts bricking the conversation into debate in the media in community groups so men recognise that in empowering groups they are not questioned. >> when it comes to women's rights and those advocating for the rites and the equality of both agenda area, how do you determine success.

unemployment rate of 10%, the numbers suggesting that you have 40% of the population living below the poverty line how do you take a moment like this and get a role movement in the city's economy. >> we have a lot of things that have changed. we have a lot of people coming in wanting to work through the process of getting grants and living here as well as new businesses that want to relocate. it won't come overnight. it will take a while. it will take a while to get things in place. we on the road are trying to rekindle all that.

as and found out how she lived the disturbing images for decades. my father never built a bomb or hit anyone with a billy club. he created a climate that allowed other people to go and do those things. >> peggy wallace kennedy is the daughter of george wallize. the president obama governor that built his reputation fighting against civil right. >> seg regation tomorrow and segregation forever. >> when you listen to your father say segregation now, and all of that. >> that's probably the most righteous thing i heard him say. >> that was not the only time her father's words and actions betrayed racial violence. she stood in the door denying entry to two students. ball own died in 2005.

her younger sister sharon remembers receiving threats of violence and death. >> i aped the phone. people are making death threats, calling names on that day. >> while it ordered state troopers to block nonviolent marchers on the prij in -- prij including a prij including a young congressmanful. >> you can't believe what you see on tv. it was horrific. in fact peggy said she never spoke to her father about his views on race, even though his hard-core conservative speeches made him one of the best known pol difference to america. wallace changed. the turning point is the 1972

campaign for president when a gunman tried to kill him. he would spend the rest of his life in a wheelchair. after reflecting on politics in the past, and seeing the pain and suffering it caused others it affected him in his fourth and final term wallis began to apologise on views on race inviting opponents to his home and office including john luize, a victim of violence. lewis moved from alabama to georgia and was elected to congress. >> we had an opportunity. i said governor why do you need an order for people to give us. he said "we had to stop you on the bridge" because there were people waiting to kill you. i said "governor, do you kill

people to stop others killing?" he didn't have an answer. i'm not convinced that governor wallize believed all the stuff he was saying. i think he used the issue of race to get ahead. >> wallis met with two students he blocked from entering the university of alabama. did your sister share with you being frightened. >> this is something that amazes me i think she never showed here or gave into that fear. she and my parents were people of great faith, and they felt they were doing the right thing and that all would be tape care

of it took another few years. it was time for her to move behind apoll guess to reconciliations. first she made the young senator as president. she encouraged me. soon peggy wallace kennedy found herself walking hand in hand across the edmund pettus bridge with congressman john luize. >> this young lady was so courageous brave and warm to greet me and it was very moving. one of the greatest honours of my life. that's how i met him. he is the epiphany when he says

love and reconciliation can heal a heart. >> all over bam there are plaques and statues. no one can change history. george wallace's deeds will be part of his legacy. his daughter hopes she can create a new legacy. >> in 2013 families that stood against each other met face to face. >> it was amazing to see, you know, how people come in 1 generation. >> they told out we wouldn't get here... >> 50 years ago martin luther king junior and the selma marchers arrested the destination, montgomery, intent of giving the governor their

petition. peggy was on the steps waiting. >> 50 years ago where was your father. >> he was up in the second floor office. >> reporter: did not meet the marcher. >> he did not meet the marchers. >> reporter: you wanted to meet them when they came back. >> yes, i did. >> reporter: why was it important for you to be a welcoming party. >> because i'm a wallis, i'm a wallis but i'm different. rrrivalts from your dad. >> from my dad. >> randall pinkston reporting, 50 years after the selma march. the state is defying the federal court, not with voting rights, but the right to marry. rennes reports. rob reynolds reports. >> reporter: this couple have been committed for nearly 2 years. the women say they had slim hopes of being married in the eyes of their state.

marriage between a man and a woman, and that the state has compelling interest in keeping to that traditional definition. that reasoning has been rented by scores of state and federal courts around the country in recent years. for many alabama's resistance is like the defines of the governor to desegregate schools. >> i say segregation now, tomorrow and forever. >> it's absolutely disappointing and quite frankly it is embarrassing. for our state to be in this position and have the state supreme court court ruling and opinion. >> the marriage is legal and cannot be undone. they'll be act i-in pushing for change. it affects people around us. it affect us there's still an issue. >> the u.s. supreme court in

the year before. southern guerrero state, once lected is processed into high grade heroin. the payoff is higher. arriving in the fields of flowers, it's easy to forget that the poppize are at the route of a lucrative and violent industry. >> the farmers who asked to hide identities faced threats from drug traffickers and authorities. . >> the farmers we met say men show up three times a year to

buy the poppy sap have to agree to whatever price is set. asking for more would be suicide. poppy farmers can earn hundreds a day. community leaders say they prefer to grow fruit and vegetables, but need good roads to get them to market. no support, they say, but there is punishment. in recent years, mexico adds government stepped up. the result, a whole harvest of poppies lost. sometimes neighbouring legal fields are damaged to. but the flowers continue to flourish. and mexican cartels are the main source of the heroin found in the united states. and with american users

demanding more of the deadly drug, a difficult journey out of these mountains is well worth if for the traffickers. it tune in for freeway, crack in the system - award-winning film-maker exposes how the threat of cocaine destroys all across the u.s. beginning at 9:00 eastern. we have weather with rebecca stevenson, and why he doesn't find being auld a
