>> the deadly crash of an amtrak train in philadelphia, a body was pulled from the wreckage today. we have a team of reporters following the latest developments. lisa stark is in washington for us. we begin with johnter rat who is in philadelphia. where do things stand at this hour? >> well, tony, good afternoon from philadelphia where there are news conferences scheduled for 2:15 and 5:00. we'll be reporting those as they happen. giving you the latest information. for now we're basing everything on a news conference that happened a couple of three hours now. in that news conference, one of

the board members revealed that they have already found and removed and already downloading data from what he called an event reporter--recorder. and they also have a forward-looking dash cam in the cab of the engine that's derailed and separated from the other cars. we're told all of that is downloaded. i think the implication is that we may have early indication, early indication of what may have gone wrong 16 hours ago when this train crashed. we're told, by the way that they're concentrating their effort apart from looking at the cars, the rails, and the human conditions of the staff on board the train they're concentrating on the issue of spade. we'll hear what they say in those news conferences this afternoon. we have 200 people injured in this crash last night. we know this because the emergency management has told us

that. and now the death toll has gone up to seven. it has unfortunately reached seven. look at those carriages and how the engine is decoupled from the rest of the train and the two first carriages, how they are badly smashed. flags are now flying at half-staff in the city of philadelphia, and around the state of pennsylvania. >> hey john what has been amtrak's response to this so far? >> well, amtrak is in a difficult situation. they own the track on which the crash occurred yesterday. so there is really not a great deal that they can say. also interestingly at this very moment in washington on the heel they're trying to trim $2.5 million off the budge of

amtrak, this comes at a time when they've been pleading for more money they did issue a statement overnight. here's what he had to say. >> a thorough investigation will take place from this incident led and amtrak will do everything in its power to assist in that investigation and will bri saddened by what's occurred. >> although the train crashed north of philadelphia station the feeling is that those who were killed, and those who are walking wounded those who would have walked away from the train immediately, may have come as far as richmond, virginia, certainly washington, d.c. and new york city and the tri-state area. they want people to call in if they. 1-800-523-9101. 1-800-523-9109. tony? >> amtrak has suspended all

train service between philadelphia and new york city. how long is that expected to last? that would impact a great number of people. >> yes, the commute this morning would have been wrecked for people trying to travel between new york city and washington, d.c. and according to the mayor of philadelphia as early or late depending on how you want to think of this, as of last night he said that he thought it would be at least a week before this stretch. of line is reopened. and it's not difficult to see why. not only do they have to continue the investigation, but then they have to move on to the clean up and then to the repair. think how much is overhead powering these trains. i don't think we'll see trains running properly on this man line according to the mayor until next week. >> i believe that first news

conference is at 2:15, we'll talk with you then. let's go to lisa stark. three questions seem obvious here. was the train going too fast? was there a breaking issue? was there operator-error? will their recorder be able to answer those questions and hopefully more? >> that will be a critical piece of evidence, tony. as you can see from the picture the locomotive was not too badly damaged, or at least it appeared. they were able to get to the event recorders. that's very good news. they're being analyzed at the amtrak operation center in delaware. and earlier today they detailed what they hoped to learn from that recorder. >> we have a forward-facing video camera in the head-end of the locomotive. we'll be looking at that. the event recorders themselves can give you information about the speed of the train any

brake applications or throttle applications that the engineer could have made. horn bell, it gives us a lot. that will be key to this investigation. a good download of those data which is being conducted will be done this afternoon. i think. >> and one key issue, of course, is speed. how fast was the train going? the speed limit on that section of rail, the curve where the train derailed is 50 mph. the question is was the train going that speed or faster? the event recorder should tell them that. another key piece of evidence is what the conductor has to say. the conductor survived this consistent. according to the mayor of philadelphia already has talked with the police interest and will certainly be interviewed by the mtsb, which has already begun to pull all the training records of the crew members, and as it does on any accident it will go back 24 hours and see what was going on with the crew

at that time. any fatigue issues, health issues, this is part of the comprehensive examination that will look at human factors and the conditions of the train, the rails, the brakes, everything that could have gone into this horrific tragedy. >> good reporters like you will be digging into the amtraks safety record. what is amtraks' safety record. >> first we should report that amtraks has record ridership and it's gone up phenom nailly over the years. and as a whole it has good record numbers. derailments crashes at crossings where they run into cars and trucks that sometimes try to beat the train. but it is not that common to lose your life on an amtrak train. this is the deadliest amtrak accident since 1999 when 11 people died in a crash in illinois. >> this is getting a lot of attention, as if should, on capitol hill right now.

we're hearing railroad fund something under way. what do we expect in that hearing? >> well, you know, amtrak has long had to go hat in hand to capitol hill. it does not have the support that it pants from the government. it's always asking for more money. and many people are capitol hill are loathe to give amtrak the money. some republicans want to privatize amtrak and take it off off the government dole entirely. the accident was mentioned at this hearing on capitol hill, and peter di it wasio, from oregon organize, the rangering tells on infrastructure committee, he said look, we're talking about cutting funding for amtrak, and his point is that we cannot forward to do this. amtrak always has a tough slog on capitol hill. >> i'm sure we'll be talking the next hour, thank you.

they are are there overseeing the concerned, those who are not making the journey ill health plays a part in that. what the white house is seeing that those who are here are important. the emirs of kuwait and qatar are here. the two heads of states are attending. the defenseman is here and the foreign minister are here. the people that americans have most contact with particularly when it comes with the operation in yemen and the battle against isil. they believe that the people overly upset on the face of it, at least that some of the heads of state respect here. they believe that they are the people around the table that can get some business done. >> yes alan, what are they discussing today at camp david? and perhaps you can give us a preview of what's on tap for tomorrow? >> well, of course, there is a lot to discuss when you get the gcc around the table. first of all is there security? they feel that it's slightly threatened. why is it slightly threatened?

bus in their views are closelying up to iran and they're also talking about isil, iraq and syria they'll talk about ongoing with weapons. barack obama is with the saudis. he'll be with everyone around the table when they sit down for dinner. it's hard to believe that that will be a relaxed affair. nobody will be kicking back talking about baseball or ice hockey they're going to be talking about what is going on in the middle east. and then when they move to camp david they'll they will be in small groups the gcc will raise the issue of it increasing more arms sales. they would like written

commitment from the americans. what the americans will do is clear the way of more arm sales. they still won't overshadow what israel gets because that's enshrined in american law. but there will be more arms sales, and the hope. that's what they want. to know that north america is there, they've got their back, and they're holding their hand. >> the death toll in nepal is 91 people after major aftershocks. the quake 7.3 quake an aftershock that rocked the country after an earthquake two weeks ago. gunmen open fired on a bus in karachi. six people on motorcycles started shooting.

were wearing uniforms. uniforms. there are silver armed groups operating in the area and it's likely to take much longer to bring a complete end to the violence. >> up next on al jazeera america celebrations in burundi, the military said that the military has been removed from power after weeks of protest. and north korea reportedly executed its defense chief. why kim jong-un sentenced his defense chief to die?

know if this is crowd control or if people are actually fighting. >> malcolm webb in burundi for us. north korea's kim jong-un has reportedly executed it's shy chief. they say that hyon yong chol dozed often during a meeting and kim jong-un said that he failed to carry out his instructions. they're describing it in terms of consolidation rather than crisis. >> our government sees such executions as a way to create a fearful atmosphere to promote consolidation of kim jong-un's

one and only regime. >> this is also leading some to question the stability of north korea's leader in kim jong-un. >> there has to be better ways to insure the order of the system rather than quick removal. this seems to indicate only the weakness the system, not the strength at all. >> unlike the case of kim jong-un's uncle who was publicly humiliated before execution this time there was no announcement. >> he was shotly heavy caliber anti-aircraft machine guns into a crowd of hundreds. it's not the first time that pyongyang has been accused of killing people in this way. there was the release of this

[ children singing ] >> those in the capital are slightly better off but face a different set of challenges. they're more than 100 children in this class, which is not out of the ordinary. for under resourced teachers it's an impossible ratio. >> it's a problem for the whole state. there is not enough to build classrooms.

food in april. >> this food is the only food for miles around, and almost none of it is fresh. if you want fresh fruits and vegetables you have to drive 50 miles that way to the nearest grocery store. proceeds from the tax will be used to fund health awareness programs like this zumba class. danny simpson was the law's primary sponsor. >> we're looking at ourselves. and for myself you know, i have to do that. back in january 2015 i weighed 235. and today i away 192. >> the tax is just 2%. they did not want to impose hardship on cash-strapped families or force drastic changes in diet. community activists helped to draff the bill. >> our young people think that unhealthy food is their source of nutrition. they think oh, a candy and chips and soda are my lunch and

breakfast. >> it was more of the marketing that was being imposed on our people from giant companies say, corn in a can is better. >> the navajo nation's newly elected president russell begaye said that western food industry and government is part to blame. >> people could sustain themselves by farming before. you would grow everything. you have livestock for meat and so forth but then you start to change everything to being preserved. >> was food healthier back then? >> eric asks his 84-year-old grandmother betty how diet has changed since she was a girl. she said that the navajo diet was healthier because the navajo nation would eat corn, melon grown on the farm. but she injected a dose of reality in that there is no
