BOLDUAN: A massive search operation is under way in the Black Sea after a Russian military plane with 92 people onboard crashed near the Olympic town of Sochi. It's believed everyone onboard was killed. Russian authorities are saying pilot error or possibly a mechanical problem could be to blame. They already seem to be ruling out terrorism. Russia observing national day of mourning right now. CNN's senior international correspondent, Matthew Chance, joins me live from Moscow. Where do things stand with the search and the investigation into what happened?</s>MATTHEW CHANCE, CNN SENIOR INTERNATIONAL CORRESPONDENT: In terms of the search, they've got teams of rescue workers or of salvage workers at this point operating in the Black Sea. Quite difficult conditions. The sea very deep where the plane went down, but they have at least four ships on the surface scouring for any sign of debris. And they've got submersibles as well and teams of divers working around the clock to try and locate the various parts of the plane. And already there have been numerous big parts of the wrecked fuselage that have located, although it's not clear at this point that the black box flight recorders have been recovered. And they will, of course, be essential determining what exactly went wrong, and also bodies pulled out of the Black Sea. They have to be identified, of course, but about 11 bodies so far of the 92 believed to be onboard were pulled out. At the moment, officials are saying they believe it isn't terrorism, more likely possibly mechanical failure, but more details in the days ahead.</s>BOLDUAN: Matthew Chance, thank you for that update. We'll keep a close eye on that as that search continues. It's a stunning allegation from one of America's strongest allies. The Israeli prime minister accusing essentially the Obama administration of colluding against the state of Israel. Now, President-elect Trump is weighing in. Details on that ahead.
