>> want to start with today's top story. and it's a video that's surfaced from a terror group vowing to strike during the winter olympics in sochi . with 17 days to go now, is russian security ready? and why are u.s. officials complaining about a lack of cooperation? let's get right to nbc's chief foreign correspondent richard engel in moscow this morning. good morning to you.
>> good morning, savannah. russian officials say they have security under control. but this latest threat does seem credible. and russian security forces are searching for one woman in particular who's gone missing whom they worried could be involved in an attack on the games.
>> reporter: the olympic torch passed today in the city in the around the world relay closing in on sochi . but terror groups are eyeing these olympics , too. a new threat has emerged from the very same suicide bombers . both now dead who attacked over the new year. in their calm, last testimony, the young men documented how they've prepared for the attack step by step . and some time later, those men, the video claimed, killed dozens of civilians at a train station and on a bus. it was just the first wave. the next attacks will bring, quote, a surprise to the olympics . security in sochi is already tighter than at most airports. president vladimir putin has said security is a national priority and that every resource will be used. but on the sunday talk shows, there's been a chorus of concerns and complaints.
>> they've now moved some 30,000 armed troops down to the region. that tells you that their level of concern is great, but we don't seem to be getting all the information we need to protect our athletes in the games. i think this needs to change. and it should change soon.
>> i would not go. and i don't think i would send my family.
>> but why attack the olympics ? mostly revenge. russia is fighting a low-level war in the caucuses. a territory less than 1,000 miles from sochi . the republic of dagastan is especially violent. and that's where the suicide bombers say they're from. the winter olympics aren't really the target, russia is. the games, analysts say, are just an opportunity to grab attention, and to try to harm vladimir putin .
>> reporter: security is only one point of u.s./ russia tension. another, of course, is edward snowden, the nsa leaker who now lives in russia with some u.s. officials suggesting he had help from russia . other officials say he acted alone.
>> richard, thank you very much.
