life of a migrant worker through their parent's eyes. and the challenges faced for a better life for kids. hi there. welcome to al jazeera america. i'm thomas drayton. a massive search and rescue mission is underway for the missing malaysia airlines passenger plane. more than 10 countries are involved. authorities can't pinpoint where the jet went down 10 days ago. two men boarded flight 370 with stolen passports. they were listed in interpol's global data base, but security officials never double-checked the list. tickets were purchased with cash in thailand. an iranian man bought the tickets, but that has not been confirmed. >> in this age of heightened security, how did passengers

with stolen passports get on the airliner. we look at some flaws in airport security. >> it's hard to believe in this day and age people can board planes with stolen passports. importantly it happens a lot. kuala lumpur never checked to see if the two passports were, indeed, stolen. last year people boarded planes a billion times without having passports screened. that's two out of five passengers whose documents are not fully checked. after 9/11 interpol built a huge data base of stolen documents over the world. it it's available to 200 countries. most countries don't bother running it through the database. it holds 1 billion documents that have been stolen. >> experts feel if the of flight

was headed to america, it's likely they would have been caught. otherwise few countries are making sure passengers are who they say they are. interpol says it's a huge hole in security. >> families with relatives on flight 370 are losing patience. demanding more information. chinese officials are fielding complaints from relatives who believe they are not being told the truth. two brothers of a texas ibm executive on the plane spoke about how they are dealing with their ordeal. >> he was an incredible brother. he still is an incredible brother. he was like a mentor, you know. we all want to know what's going on, and we are just waiting, you know, just like everybody, to finally hear something to help us with this situation. >> it is a tough situation. once the plane is found,

malaysia airlines says it will fly two family members to each missing passenger. any new developments will be brought as soon as they come in. >> russia is working on a counterproposal to a u.s. plan. russian forces are strengthening their control over the crimea peninsula. a referendum will be held in a few days as to whether crimea should split off and become part of russia. the u.n. and others declared the vote illegal. russia doesn't seem to be loosening its control over the region. >> in military base a 4519 ukranian soldiers are reinforcing their defenses. they don't know if the russians will scale the walls or come through the gates. there's a new directive, whether ukrainian soldiers stand outside or inside. s must be at the ready.

pressure began last week. we filled as a mob of pro-russian activists storm the base. they demanded that the ukrainians surrender and let the troops through the gate. >> this is the same gate, six days later. they've reinforced the gate with soldiers. not only that, this gate is new. this is a heavy-duty truck filled with cement trucks to block anyone from going in. the public grounds are empty. they have hunkered down. this officer has four kids who live on the edge of the base, and he shows me how they'll protect him. >> they can slow them down. in a flight it will give them a few seconds. >> his commander has been negotiating with the russians. he beliefs the base has some

time, at least until sunday, the timeful referendum. he worries the time is running out. >> translation: my troops and i are under pressure outline the time. there are different provocations and ultimatums. >> he shows me the latest, "stand down and hand over all weapons." would you call what the russians are doing an occupation. >> translation: it's a real occupation. we shouldn't pretend otherwise. >> when the russian troops arrived the ukrainians were under orders not to shoot. they resisted the occupation however they could. the order still stands. >> we'll protect the base, absolutely. not... >> this major admits there's not much his troop can do. all they can do is resist a russian demand to defect. >> what was the base's response to the request. >> absolutely not.

why not. we have taken an oath, we are fulfilling our duty. >> they are fulfilling their duty as long as they can. but they are not sure how long the lock will hold. >> ukraine's new prime minister is scheduled to meet with president obama in washington. former n.s.a. contractors edward snowden delivered an address in the u.s., speaking by video conference at the music and technology meeting south by south-west in austin texas. he called for more awareness for cyber security, and said the technology says it needs to expand encryption services. edward snowden is living in russia to avoid u.n. prosecutions for dealing with this. >> the pentagon was accused of interfering in brigadier general

case, where he sexually assaulted a captain. he was pushed to plea to show the military was cracking down on sexual abuse cases. the defense team must decide whether to keep going with the plea. legislation will oppose half-a-dozen changes it the way the army handles changes. the bill enables them to have a say in whether the matter is heard in the civil or military court. the house will take up the measure. >> inside the venezuelan opposition. what one leaders says needs to be done to avoid a civil war in his country. al jazeera uncovering new numbers into pan am flight 103. who may have been behind the

>> welcome back. the taliban is threatening to disrupt afghanistan's presidential elections next month of the the united states is manipulating the vote. two campaign workers have been killed in one presidential candidate was assaulted during the lead-up to the april 5th elections. if the elections take place successfully it will be the first transition of power in afghanistan's history. the u.s. is watching the vote closely. the next president will decide whether to sign a security

agreement, allowing american troops to stay after this year. >> the grow violence at anti-government rallies is deepening divisions amongst opposition groups. moderates fear the violence could get out of role. paul beban is in caracas, and he spoke to a leader of venezuela's opposition most. >> you said the government has to change your course, and if it doesn't change your the conflict will get worse. what do you mean? are we talking about civil war, armed conflict? >> translation: it's profile what i want to avoid, a civil war between venezuelans, that's why i'm asking the government to change your. if they don't change your their attitude, and maintain their position, because they are talking about dialogue, but it's a mopo log where they -- monio log, where they assist an if a model doesn't work, we may be

facing an explosion. >> you asked for an end to violent clashes, but they continue. >>. >> translation: some in the opposition might thing that throwing stones and building barricades is the way to fight. those people, which no one can control now will stop when they realise the mechanism they are using to protest is not working. the government will do what they can to keep going. if they are not there, they can infiltrate the program. without a doubt, the government can profit from this. it's not something we haven't seen before. >> you expressed a lot of faith in the democratic process. the opposition does not have enough support for this to turn into ukraine. they are not going to topple the government. will it go towards something like syria. will there be more violence against venezuelan citizens by its government to stop the protesting? >> i wouldn't want that.

i also don't think it's the same case. ukraine, syria, egypt - it's hard to compare. they are different cases, cultures, customs. i think we are entering a crucial moment. we are waiting to see if there's a shift in the government's position or attitude, where they continue further repress or do they want the peace they are preaching about on tv. >> paul beban reporting. >> 25 years ago everyone on board pan am flight 103 was killed when the plane exploded over lockerbie scotland. iran was likely responsible for the bombing, not libya. >> one man, a libyan was tried and found guilty. documents obtained by al jazeera, and verified reveal iran's secret service were involved in the attack. details of the investigation will be revealed in an exclusive al jazeera report tuesday night.

the program's producer about why this didn't come to light earlier. >> i think it's a question the authorities in the u.k. and the u.s. maybe will have to answer after the show is aired. all the blame was pinned upon a man, a man whom the case against him has been shown and agreed by many to be flawed, and a serious miscarriage of justice appears to have taken place. the fact that the idea for all the responsibility is on the shulders of one individual is ludicrous. >> you can watch "lockerbie - what really happened." >> boston are implementing security measures for the

marathon. bags and coolers will not be banned, but will be subject to search. two bombs exploded near the finish line last year, killing many and injury many. >> 59 businesses paid tax in the first month of selling legal marijuana. state collects 30% on pot sales at colorado dispensaries. it is being viewed as a test case as to how it effects crime and revenue. >> eric holder is calling the increase in heroin death a crisis. >> the cycle of heroin abuse begins with prescription opiate abuse. the transition to and increase in heroin abuse is sad but not inpredictable simply tom of the increase in prescription drug abuse that we have seen over the

past decade. eric holder is encouraging first responders to carry a drug that will reverse the effects of an overdose. 17 states in the district of columbia allow it to be sold to the public. >> former olympic star oscar pistorius cried and threw up in court after hearing details of the autopsy. the testimony was so graphic the judge barred it from being broadcast. the defense maintains oscar pistorius mistook reeva steenkamp for an intruder. he faces life in prison. >> we have a warm-up on the way for the east. it is a cool down for the west. not only a cool down, but drying out as well. snow levels will come down, that will hold on to the snow pack that is in place.

>> despite the fact that nascar's fan base is one of the largest in the country, the one aspect of that sport that is lagging is diversity. as jessica taff reports, it's an issue nascar admits and is trying to address. >> this is not your grandfather's nascar. the sport of lefthand turns and a good old boys mentality is putting both hands on the wheel and steering it towards a new audience. >> the diversity platform is important. we recognise that america is a demographically diverse place, and that car wants to be diverse in every aspect of our business. >> including the front office with matt segal becoming the first african american president. jamie is an engineer, and dion

the second year driver, a regional racing series says the toughest transition into the sport is not the driving but the language barrier. >> i feel like all this speaking in english and communication for the team - we need to work on it, and we work on it last year, and i feel like all this adaptation is it decent right now. >> nascar's drive to diversity is not about forgetting about the legends of the past or bypassing those on the sport. it's about looking to the future, making the sport more representative of what the world looks like today. it has one of the largest fan bases. it's the second most popular tv sports. the criticism is it's made of 60% men, and 80% are white.

mostly from southern and midwestern state. >> success moves it in the right direction. the rookie of the year says it's a ways to go. >> when i encounter the bad and the negative side to it, and racism, i was too young to understand it. i mean, i get hand gestures sloane out, slurring thrown out. i was like, "okay, what is that." my parents - they understood it, of course. they told me to go out and win again. okay, i'd do it. we'd go out the next weekend and win. they'd be quiet or stop complaining and finally say, "the kid is good. it's >> it's open to anybody who needs the requirements. drivers must be u.s. citizens or resident permanent aliens between the age of 15 or 26. they have to be a female.
