this is al jazeera america live in new york city. i'm del walters. egypt's president is in london today talking security with the british prime minister about the crash of that russian jet liner over the skies of egypt. british officials now saying it looks increasingly likely that the russian plane was brought down by a bomb. because of that intelligence, the u.k., ireland, and several ire lines suspending their flights to the red sea airport. >> translator: about ten months ago, our friends in u.k. requested us to assure the security measures taken. at that time, we invited british delegations to take firsthand information about the security measures taken across all of our

airports. >> of course i cannot be sure, my experts cannot be sure, that it was a terrorist bomb that brought down that russian plane. but if the intelligence is and the judgment is, that that is a more likely than not outcome, then i think it's right to act in the way that i did. >> officials are working to get the stranded tourists out of egypt. flights back to the u.k. could resume on friday. >> this can happen anywhere in the world nowadays, and i feel really sorry for the egyptians, because i know they have had a real drop in the number of tourists that come into egypt, and i personally think you need to live your life and not let the terrorists win. >> reporter: and vladimir putin telling british officials that they are wrong, and to wait for the official results before saying outright that a bomb was responsible. lisa stark has more on the investigation. >> reporter: so the big

question, was a bomb planted on board this plane at the airport? the associated press is reporting that some communications have been intercepted that seem to indicate that a rebel group, affiliated with isil, but located in the sinai, did plant a bomb on board this plane, but we should stress that there have been no definitive conclusions reached yet. egyptian investigators have not officially determined whether an explosion or mechanical problem brought down the plane, but the british government says information now points to a bomb. >> we have concluded that there is a significant possibility that that crash was caused by an explosive device on board the aircraft. >> reporter: 20,000 britains are vacationing in the area. >> there will be no u.k. passenger flights out to the

area from now. passengers who are on the ground will be returned to the u.k. >> reporter: the state department says it's not jumping to any conclusions, but has now restricted u.s. embassy employees from traveling to the area. >> it's the responsible thing to do for the government to tell its workers don't go to the sinai right now. >> reporter: before the accident, the faa had issued an alert to avoid flying below 26,000 feet in the area, warning: >> there are no u.s. carriers that regularly operate out of the sinai peninsula. and in fact, the airport in question is in fact the last

point of departure into the united states for any airline. >> reporter: united airlines does fly over the sinai, the only u.s. carrier to do so, with flights to dubai and kuwait. it is diverting until further notice. investigators have both of the flight's black boxes. it says the voice recorder was damaged and will take more work to desighser. a u.s. military satellite deflected a heat flash around the jet as it broke up around nearly 30,000 feet. does that indicate a bomb in bob francis says the wreckage will reveal the answers. >> if it was something that was strong enough to bring the aircraft down it is going to do a lot of wreckage to the airframe. >> reporter: one thing that is

fairly certain was this jet was not brought down by a missile. rebel groups in the sinai simply do not have the technology to attack a plane at cruise altitude, and the u.s. military satellite detected no evidence of a missile launch. the death toll from the building collapse in pakistan now rising to 23. the building came down in lahore. local officials saying 150 people were in the building at the time. it was under construction. >> >> translator: a full story was being constructed. at the moment we have our emphasis on rescuing more people. >> pakistan was hit by a powerful earthquake more than a week ago. it's not clear whether that played a role in this collapse. today the hacking group anonymous is promising to pull the hoods off of a thousand

members of the ku klux klan. already members of anonymous and their supports taking to the streets of knew -- new zealand and australia. >> we are anonymous. >> reporter: a force for good or evil? exposing criminals or harming innocent people? the mysterious activist hacking group anonymous, some consider cyber terrorists, others digital crusaders. >> does that mean in 100% of the time their interventions are positive? no. but the motivations that drive them are driven by noble intentions. >> reporter: this woman has studied the group for years, formed nearly a decade ago, she says they are now largely known for pushing for social justice.

launching cyber attacks. hacking to reveal secret, and demand attention. whether it's about police brutality or online bullying. >> we didn't have this kind of support everything happens, but now that we have people listening, it's like a miracle. >> reporter: in ohio a 16-year-old girl was allegedly raped in 2012. there were concerns of a coverup to protect football stars. anonymous uncovered tweets and even an alleged video of the crime. two players were convicted and the school superintendent resigned. >> this community is fixing things. this community is holding people accountable. >> reporter: but anonymous is also a loose collective, impossible to hold accountable, and at times they are wrong, like when they misidentified

michelle brown's killer in ferguson, missouri. or even with the kkk. early leaks of the names of alleged members appear to be false, causing the group within anonymous that have been working on the klan hack to distense themselves from the claims. it's claims can be hard to track and confirm. critics say it's vigilantism is at times misguided, raising troubling questions about a group that shrouds its in anonymity can be so willing to expose others. >> there is a lot of internal bickering about the correct methods, especially along the lines of illegal, versus legal methods. there is a strong warning today in california, don't eat certain types of crab. just moments ago the california fish and game commission unanimously voting to

temporarily ban recreational grab fishes. members they the crabs are in high toxins that are dangerous to safety. but commercial fishing is still being allowed for now. >> reporter: dungeon esz crab is a thanksgiving tradition for years. now this man waits to see when the season will begin. >> we're on stand by, you know? there's not much you can really do any way this time of year. there's not a lot of alternative fisheries for us this time of year. >> reporter: the department of health is concerned about dangerous neurotoxins in the crab. and warn from eating the crabs.

sport fishermen who take tourists out on the bay is anxious about this first-time health concern that could cripple his business. >> i don't even want to tell you what i'm going to lose this weekend in bookings. the boat was filled up saturday and sunday, and, you know, we can't kill people. >> reporter: he says he'll lose $5,000 a day. the state says commercial crabbing brings in $60 million a year. health officials say tests show high levels of acid in crabs, a naturally occurring poison that can lead to stomach distress and in severe cases seizures, coma, or even death. this crab pot hasn't been in the water since last season, and there's no telling if it will get back in any time soon. it depends on when the water temperature drops, and the level of neurotoxins in the crabs subside. scientists say unusually warm water has lead to blooms of

algae that produce the poison. this crab is from north of the bay area. >> we're going to have explain that it's coming from washington and it's safe, and then they are going to wonder why they are paying so much. >> reporter: he says the cost will go up if the crab isn't local. this man isn't fretting too much. >> it is what it is, we have to protect the consumers. we don't want anyone to get sick. >> reporter: the consumer may pay a little more, and the fishermen may earn a little less in the name of keeping food safe. president obama is hosting native american leaders in this washington, d.c. today. plus corral reefs are a vital part of the ocean. we'll tell you how scientists in

florida are trying to bring them back before more die off.

>> this is one of the most important sites in the century. >> this linked the mafia and the church. >> why do you think you didn't get the medal of honor? >> i can't allow you not to go into that because that is

your job. >> we gonna bring this city back one note at a time. >> proudest moment in my life. high schools that may want to change what some say are logos offensive to native americans may now have some help. there are till about 2,000 high school with native american names and mascots. and that adidas announcement coming this morning in washington. there are mayor problems that have to be resolved on their reservations.

>> reporter: the ground i'm standing on used to be a sidewalk, the area behind me was a place to park buses and repair them. but for the last 30 years, students here on this reservation have had to use this as a school, with a waiting list of more than a hundred schools that need replacement. officials say the band aid fixes can only hold up for so long. funding for education is a big priority for tribal nations. it's also one of the issues president obama will discuss today as he meets with native american leaders. this is the seventh year he has held such a meeting, and representatives from more than 500 tribes will be there. president obama has made native american issues a key part of his time in office. we spoke to two tribes in minnesota to find out if those initiatives have made difference on the ground.

here a tribal council member says he has seen plenty of signs of progress over the last seven years. >> he did his -- his part to -- to help us success. he helped us with education. he helped us with infrastructure development. we have got programs here that are a direct result of -- of -- of the obama administration. >> reporter: since the president took office, funding for many programs in indian country has increased, but for some communities like the leach lake reservation, two hours north, the money hasn't trickled down. if you were in d.c. with the other tribal leaders right now, what would you be asking obama? >> i would ask him right out to give us the funding so we can build a school, and i wound invite him here so he can see what our building looks like. that's what i would do. >> reporter: school officials say they hope the funding comes

mexico's war on drugs. >> reporter: it's a landmark decision that mexican advocates of legalized pot have been waiting for. mexico's supreme court ruled that individuals have the right to grow and consume marijuana for personal use. the ruling only applies to the plaintiffs who took this case to court and does not approve the sale or commercial production of marijuana, and it does not strike down mexico's stringent drug laws, but it may pave the way for the legalization of marijuana in mexico. >> translator: from a constitutional interpretation no reason exists in which the answer of the state to the consumption of marijuana is the see collusion and absolute prohibition of its consumption. >> reporter: it's a also a decision many mexicans like this family have been waiting for. grace suffers from a severe form of epilepsy, that causes intense seizures has been treated with

medical marijuana. grace's mother had to secure permission from a judge to get the drug, she hopes the rules will make it accessible to families like hers. >> translator: we believe we will be just a step away from the authorization of medicinal use too. >> reporter: the country has a violent history with drug lords. >> translator: we are not going to allow it. the mexican people are not going to allow it to be a vicious mexican society. >> reporter: but for now advocates of marijuana legalization are celebrating what they say is a huge step forward. >> translator: prohibition has already generated too many widows, orphans and pain in mexico society. it hasn't achieved any of its goals, so don't cry over prohibition. the world coral reefs are

dying an at alarming rate. now scientists in the florida keys say they have found a way to reverse the trend. >> i thought coral scientists needed self-help groups because they saw what was happening under water years ahead of what was happening on land. >> reporter: scientists are worried about scenes like these. over the past 30 years more than a quarter of the earth's corals have disappeared. marine biologist and his team at the mott tropical laboratory are racing to try to reverse the trend. ten years ago he accidentally discovered if you cut coral into

tiny fragments it stimulates it to grow up to 10 times its normal rate. >> these were just put today. and just a couple of polyps that you can see, but in just a few weeks instead of a few years these will start growing, and these are just a month or two old, and already they have grown to almost fill out that base. >> reporter: this is a game changer. >> this is a real game changer for the reef-building corals. >> reporter: they are arranged on small rocks in sea water nurseries. using this method, dr. von says his team can produce thousands of fragments in days. these fragments are cut from corals which possess genetic characteristics that can give them a better chance of survival. in nature this coral would take about 15 years to reproduce and there's about a one in a million chance that it would be able to do so, but this new technology

means that dr. von and his team are available to grow these corals to this size in less than a year. once the corals reach a certain size, they are then transplanted on to dying reefs. it's now one of the largest coral restoration projects of its kind. thanks to government grants and private donations, next year they plan to expand the program and double the amount of reef restoration. over the next decade, dr. von hopes to restore more than a thousand acres of florida's reefs. throughout his career he has seen some coral species nearly vanish, but now he is optimistic. >> we can't wait a hundred years that they may come back on their own. we want to head start them so we'll have corals here for a long time. >> reporter: rachel levine, al jazeera, the florida keys.

and we'll tell you who nasa wants to hire as its plans its next mission to the final frontier. >> we made a promise to these heroes... this is one promise americans need to keep.

>> i've been asked to keep my voice down cause we are so close to the isil position >> who is in charge, and are they going to be held to accout? >> but know we're following the research team into the fire >> they're learning how to practice democracy...

>> ...just seen tear gas being thrown... >> ...glad sombody care about us man... >> several human workers were kidnapped... >> this is what's left of the hospital >> is a crime that's under reported... >> what do you think... >> we're making history right now... >> al jazeera america >> this is al jazeera america live from new york. >> at 7:00 - "news roundup". tony harris gives you a fast-paced recap of the day's events. >> this is the first line of defense. >> we have an exclusive story tonight. >> then at 8:00 - john seigenthaler brings you the top stories from across america. >> the question is, will these dams hold? >> and at 9:00 - >> i'm ali velshi, on target tonight... >> ali velshi on target. digging deeper into the issues that matter. >> i'm trying to get a sense for what iranians are feeling. ♪ we could find out more today about the future of travel to mars. nasa set to unveil what it calls

key scientific findings on the red planet's atmosphere. and would boost the hopes of sending a manned mission to mars in the next 15 to 20 years. and every kid dreams of being an astronaut. now nasa is accepting applications for their next wave of space travellers. >> reporter: nasa is looking for a few good people to make a very long trip. >> i want you to apply for nasa's astronaut program. >> reporter: the plan is sending astronautss into the international space station, missions to moon, and eventually the red planet. >> by soliciting new astronaut applications now, they are

trying to show they are serious about these plans, and that they intend to use these people for decades to come. >> reporter: three years ago it put out a similar request, and got more than 6,000 responses. nasa has grown in popularity in the social media age. from the orion spacecraft flight test, to the first fly-by of pluto, but since grounding its space shuttle program in 2011, there has been an exodus of astronauts and other agency workers. during the peak of its space shuttle area, nasa had almost 150 astronauts. today it has just 47. >> there was a lot of turn over, a lot of people moved on because they knew there would be less fight opportunities, so this is an opportunity to get a new crop, and start ramping them up in preparation for these

missions. >> reporter: applications will be accepted starting mid-december, the lucky hires will be announced in 2017. well the college board just making it even more stressful for you high school seniors waiting to find out if you are going to get into the college of your choice. a computer problem has delayed sending test results to schools with early admission deadlines. the college board is reaching out to those schools to make sure they know it is not the fault of the students. and some good news for those of you too lazy to rake your leaves. leaving the leaves can benefit animals and lawns. it's important habitat for butterflies and chip monks. scientists say raking disturbed the ecosystem. thanks for watching. i'm del walters in new york. the news continues live from london, we'll have the latest on that crash of that russian
