would jeopardize an entire industry. 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 and about the crash of that russian jet liner over the skies of egypt. british officials saying it looks increasingly likely that the russian jet was brought down by a bomb. because of that intelligence, the u.k., ireland, and several airlines sus -- suspending their flights to the red sea resort. >> translator: about ten months ago, our friends in the u.k. requested us to assure the security measures taken in sharm el sheikh. we invited british delegations to come investigate our efforts.

>> i cannot be sure, our experts cannot be sure that it was terrorist bomb that brought down that russian plane, but if the intelligence and 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 now working to get the thousands of stranded tourists out of sharm el sheikh. the british transport secretary saying flights back to the u.k. could resume on friday. >> nowadays this can happen anywhere in the world, and i feel really sorry for the egyptians because i know they have had a real drop in the number of tourists nowadays, and i personally think you need to live your life and not let the terrorists win. 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. jamie mcintyre standing by live at the pentagon. jamie what are u.s. officials saying specifically about those

reports that it may have been a bomb that brought the plane down. >> reporter: well, first of all the pentagon and the u.s. military was able to determine using overhead satellites that no missile was fired. these are satellites specifically designed to detect missile launches. so they have been able to rule that out. and they did see a heat signature from the plane before it went down. the u.s. has not reached a conclusion that a bomb took this plane down. it has not even reached a formal intelligence assessment about what is likely and unlikely. what you have been hearing and what the british government is basing its caution on is chatter, come communications between various groups in the region. and i have to tell you from experience that that kind of chatter is notoriously inaccurate, subject to interpretation and misinterpretation. one of the reasons that the u.s.

was so convinced that saddam hussein has weapons of mass destruction, was because they overheard a lot of chatter about it. after they got in there, they realized what had happened is many of saddam hussein's people that worked under them were afraid to admit they did not have those weapons. so the u.s. has not issued any statement or come to any official conclusion about the cause of this, whether it was in fact a terrorist act, or whether it was a tragic aviation accident. >> jamie several european countries banning their flights temporarily into sharm el sheikh. is the u.s. planning to do the same? >> reporter: well, there are no flights that go directly from there to the united states.

but what the british government has done is something they are doing out of prudence, if the there's a suggestion that maybe there is a threat, discretion may be to ere on the side of caution. however, officials here say it's irresponsible, really, to jump to the conclusion that there was a bomb, based on this kind of chatter when there will be hard evidence at some point, because the plane did not come down in the water, it landed on the ground, the wreckage is there, the real evidence of whether this was a bomb or something else will be in that wreckage on the ground. there will be hard evidence, and u.s. officials say we should wait for that. >> and those planes also being told to fly at least 26,000 feet anyway. jamie thank you very much. former accident investigator says it is impossible to make a determination at this early stage about just what brought down that plane. >> they are wisely acting under

an abundance of caution. it's going to be the physical evidence at the scene that is going to help make that final determination, and that's going to take a little bit of time. i think it's extremely prudent as far as how they are approaching it. the approach is going to be, if it was a bomb did it come through ramp workers or was it a passenger that brought it on board in the passenger cabin with them, through screening. so if that's the case, they have a significant breach in their security system that needs to be re-evaluated. the death toll from that building collapse in pakistan has now risen to 23, another 80 people have been injured. that is when a building came down in lahore. local officials say 150 people were inside the billing at the time, and the building was under

construction. >> translator: a full story was being constructed. and it had not been calculated whether the existing building could bare the load or not. but at the moment we have our emphasis on rescuing more people. >> pakistan was hit by that powerful earthquake more than a week ago. it's not clear if that played a role in this collapse. today the hacking group anonymous is threatening to pull the hoods off of a thousand members of the ku klux klan. they are taking part in a campaign that they are calling the million masked march. as jonathan betz reports this isn't the first time anonymous has drawn international attention for its actions. >> reporter: a force for good or evil? exposing criminals, or harming innocent people? the mistierous activist hacking

group anonymous, some consider cyber terrorists, others digital crusaders. >> does that mean in 100 krrs of the time, their interventions are positive? no. but the motivations that drive them are driven by noble intentions. >> reporter: gabriel la has sfudyed 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 secrets, and demand attention. whether it's about police brutality, or online bullying. >> we didn't have this kind of support when everything happened, but now that we do have a lot of support, and we do have people listening, it's like a miracle. >> reporter: in ohio a 16-year-old girl was allege ldly raped in 2012. there were concerns of koovrup to protect high school football stars.

anonymous helped identify suspects, uncovered deleted tweets and even an alleged video of the crime. two players were convicted and the school's superintendent resigned. >> this community is fixing things. this community is holding people accountable. >> reporter: but anonymous is also a loose collective. and at times they are wrong, like when they misidentified michael 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 has been working on the klan hack to distance themselves from leaks of those names. it's claims can be hard to track and confirm. critics say vigilantism is at times misguiding, raising troubles questions about how a

group that shrouds itself in anonymity can be so willing to expose others. >> there's a lot of internal bickering about the correct methoding. there is a strong warning today in california, don't eat certain types of crab. just a short time ago, the california fish and game commission unanimously voting to temporarily ban recreational crab fishing along the pacific coast. members say the crabs are high in toxins that can be dangerous. lisa bernard talks to fishermen who are worried about their industry. >> reporter: jason is one of the fishermen who usually heads out in mid-november to hall inasmuch as his boat will carry.

but now he waits to see when the season will begin. >> we're on stand by. there's not much you can do anyway this time of year. there are not a lot of alternative fisheries for guys like us this time of year. >> reporter: the department of public health is concerned about dangerous neuro toxins in the grabs, and is advising that people avoid eating the crabs in the area. a sport fisherman who takes 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 saturday and sunday, and, you know, you can't kill people. >> reporter: he did tell us. 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 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 when the level of neurotoxins in the grabs subside. scientists say unusually warm water caused in part by el niño has lead to blooms of algae that produce the poison. this restaurant manager says customerings have started calling and asking where the cashes he is serving come from. >> we're going to have to explain that it is coming from washington and it's safe, and then they are going to wonder why they are paying so much. >> reporter: he says the costs will go up if the crab isn't local. >> you know it is what it is. we have to protect the consumers. we docket want anyone to get

sick. >> how many you got there? >> reporter: the consumer may pay a little more and the fishermen may earn a little less in the name of keeping food safe. lisa bernard, al jazeera, san francisco. president obama is hosting native american leaders in washington today. we'll take a look at one tribe that says it needs more help from the government. plus we'll tell you how scientists in florida are trying to revive coral reefs before even more die off. ♪ ♪

a quarter of the world's corals have disappeared. this marine biologist and his team are racing to try to reverse the alarming loss. ten years ago he accidentally discovered that if you cut coral into tiny fagments it stimulates it to grow up to 50 times its normal rate. >> so these were just cut today, and as you can see these are very tiny pieces, and just a couple of polyps you can see that are alive. 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: so this is a game changer? >> this is a real game changer for the reef-building corals. >> reporter: the coral fragments

thousand acres of florida's reefs. throughout his career, dr. von has seen some corral species nearly vanish, but now he's optimistic. >> we can't wait a hundred years that it might be a cycle that they will come back on their own. we want to headquarter them by planting thousands if not millions of tiny ones so we'll have corals here for a long time. looking for the next generation in space. who nasa is looking to hire as it plans its next mission to the final frontier.
