but the kings of two key allies aren't there. and dozens killed in pakistan after gunmen opened fire on a bus. ♪ you are watching al jazeera america. and live from new york city. i'm morgan radford. investigators are at the scene of a deadly train derailment in philadelphia. at least six people are dead and dozens were hurt in the crash. pennsylvania's governor has ordered all flags to be flown at half staff. we have a team of reporters following the latest developments. we have lisa stark live for us in washington but we begin with john terrett who is live in philadelphia. where do things stand at this

hour? >> reporter: good afternoon to you, morgan. we have had a news conference from various dignitaries who have given the latest information. the most information we got was from the board member of the ntsb, the group is now on the ground here. he confirmed that they arrived between 4:00 and 5:00 this morning. and most interestingly, robert tells us that they are already looking into data from what he called an event recorder on the train. now this is like a black box that aircraft has. trains have these as well and they provide all sorts of data for crash investigators to look into to work out what was happening on board the train at the point that it came off of the rails. also he tells us there is a forward-looking camera in the front of the cab as well and they are investigating that as

well. as we know 200 people were yired in this crash. the head of the emergency management division here in the city told us that. they were treated at hospitals all over the city mostly for injuries to their limbs, although roughly half of those people have been let go. certainly from one of the facilities that they were taken to, many according to the doctor in charge are still in critical condition. and six people lost their lives in this crash. you have seen the pictures you are looking at them now, the engine that has completely detached itself and seven other cars. flags are now flying at half fast in this city and in this state. >> john, you mentioned what the officials of the city had to say and what the ntsb said but how has amtrak responded to all of this? >> amtrak is in a very difficult position because this was their train. this is their track.

so they haven't said a great deal in the early stages of this investigation. they have said that they are very sorry for the deaths and injuries that occurred and that they will work with the families and friends of those on board the train to find out what happened as quickly as possible. within the past couple of hours we have heard something very similar from the amtrak chairman of the board. here is what he had to say in philadelphia a short time ago. >> a thorough investigation will take place from this incident lead by the ntsb and amtrak will do everything in its power to assist in that investigation, and has brought every resource to support that effort. we are very saddenedly what has occurred. >> reporter: although the train crashed just north of the philadelphia station it began in richmond virginia and would have picked up the bulk of its

passengers in washington, d.c. the feeling is many of the people who might have been walking wounded who were on the train but left it almost immediately, or those who were unfortunately killed may come from anywhere along that line. to amtrak has issued a hot line for people to call if they are concerned about relatives or friends, and even if they were on that train and walked away. they want to hear from those people too. here is the number. it is an 800 one. morgan? >> john briefly before we let you go we know amtrak has suspended all train service between philadelphia and new york. how long is that expected to last? >> reporter: well according to the mayor of the city of philadelphia speaking as late as last night when we gave his first news conference he made it very clear that in his

opinion the track here north of philadelphia is not going to reopen for at least the next week. and if you look at those pictures it's pretty easy to understand why. they have to continue the investigation, clear up and then repair. so the thought of this track reopening before friday seems pretty impossible to believe. morgan? >> john terrett joining us live from philadelphia. thanks for being with us. let's turn live now to lisa stark from washington. we understand that president obama has also commented on the derailment. what did he have to say? >> reporter: he issued a statement just a short time ago, the president saying quote, michelle and i are shocked and deeply saddened to hear of the derailment, our prayers and thoughts go out to the family and friends of those on board. this very busy line is a way of life for many in d.c. and he

also come mentioned the fire police and medical personnel for their efforts to save lives. in a news conference the mayor indicated that that effort to make sure that all are accounted for still continues. they are combing through the wreckage to make sure no one is still on board that train. >> help me understand some of the logistics. as john just mentioned the event recorder is currently being analyzed. but how critical is the information that we glean from that recorder? >> reporter: that is likely to be a crucial piece of information. you can see from the pictures that the engine doesn't appear to be too badly damaged and they were able to get the event recorder. hopefully that wor ward-facing camera as well off of it. the recorder is now with amtrak in delaware. they are looking at the data. the ntsb board member detailed what they think that recorder might show. >> we have a forward-facing

video camera that is in the head end of the locomotive so we will be looking at that. we will be -- the event recorders themselves can give you information about the speed of the train, any brake applications, throttle applications that the engineer could have made horn bell it can give us a lot. so that will be key to the investigation is a good download of those data which is being conducted, will be done this afternoon, i think. >> reporter: so as he said this afternoon we may have more answers later today of that recorder. one key thing will be the speed of the train. this was a curve where the train detailed. the speed is supposed to be 30 miles an hour. the recorder will tell investigators whether the train was going the appropriate speed or more lickly. and we understand the conductor survived. has talked to the philadelphia police. will definitely be interviewed

by the ntsb and the ntsb says it is already pulling the training records also for the crew on board. this is all something they do at every accident they look at every accident from crew performance to the rails to the train cars itself to the track signals. they're having an organizational meeting as we speak to form these different investigative groups and they will be out each doing their own piece of work to put the puzzle together. >> lisa thank you so much. the vatican today took steps towards officially recognizing palestine as a state. they finalized a treaty the first legal document negotiated with the palestinian authority. meanwhile president obama is meeting with saudi arabia's crown prince and the deputy crown prince right now at the white house. they are anong the representatives from six gulf

states visiting washington to discuss some pretty big topics including the war in yemen. alan fisher is live at the white house right now. alan what is the white house saying about the absence of the saudi king and other leaders as well. >> reporter: the saudi king is perhaps the most high profile person not here. but he is at the moment leading a country that is carrying out military operations in yemen, so it's almost understandable he is not here. a lot has been made of the six gcc countries there are only two heads of state that are here. but those that are here are high-profile players. take for example, the saudi delegation. essentially what they have is the foreign minister and the defense minister both of whom will be highly involved in any

discussions that go on here and at camp david on thursday. there is going to be a lot of ground covered. yemen will be discussed. the talks with iran and the battle with isis will be discussed. the ones that are here are the ones that are involved day-to-day discussing with the americans of the steps forward in all of these areas. >> a lot of topics being discussed. alan thanks so much for being with us. the death toll in nepal is now up to 91 people after a major aftershock. more than 2400 were injured in the wake of the 7.3 quake. the aftershock rocked the country just two weeks after a quake killed more than 8,000 people. in pakistan 43 people have been killed after gunmen opened fire on a bus. six men approached on
