There are many security fears in sochi, especially after that dramatic scare in the skies right as the opening ceremonies kicked off. ABC's chief investigative correspondent Brian Ross with the details on what appeared to be an airplane hijacking and you have developments this morning happening overnight. Russian officials say police killed five suspected terrorists afternoon a standoff in the capital of dagestan. All connected to previous suicide attacks. As for the attempted hijacking, it all unfolded just as the opening ceremonies were getting underway. And for a short time, it had echoes of the 9/11 terror attacks on New York and Washington. High drama surrounded the incident, underscoring ongoing concerns about olympic security. Turkish jet fighters were scrambled, and once the passenger jet landed in istanbul, a police S.W.A.T. Team sneaked on board. They identified the hijacker as a 45-year-old Ukrainian man who broke into the cockpit. Claimed to have a bomb and demanded the release of prisoners in Ukraine. No bomb was found, and the quick-thinking crew tricked him into thinking it landed in sochi. But what if it had been successful? The plane was heading for sochi. The opening ceremonies had begun when the reports came of a hijacking in progress. Russian helicopters patrolled the air space over the olympic village, and anti-aircraft missile batteries were ready to shoot down the passenger jet if necessary. Clearly if an aircraft is heading for a ground target, it's totally plausible to think that someone might be given the order to fire to take down a commercial plane. It came just days after the U.S. Authorities warned of a possible plot to explode a bomb on a jet liner heading into sochi. Terrorists may have found a way to assemble a small bomb using explosives packed into toothpaste tubes. They were banned on carry on flights to Russia this week. Officials told ABC news the plot may also involve tiny detonators obtained from islamist fighters in Syria. The effort to put bomb on an airplane in and around sochi an ongoing concern. Russian intelligence agencies are looking very closely at it. In the end, the first weekend of the olympics has gone off without a hitch. But authorities say it's far too soon to let down their guard. The islamist terrorists have threatened to disrupt these game S. For "This week," Brian Ross, ABC news, New York. Thanks to Brian. Let's bring in congressman Mike Rogers, chair of the house intelligence committee. He joins us from London. We saw that security scare Friday in Brian's report, and we know there's still an ongoing concern despite the fact that it might feel okay right now. You get intelligence briefs and intelligence notifications every day. What should we be concerned about right now? Yeah, first of all, the guards, Gates and guns portion of this is unparalleled for an olympic games. So the Russians have been very good about that physical security presence, an outer ring and then have had inner rings of security. So what your reporter was discussing is the closest proximity. You won't see the guards, Gates and guns. That's pushed out. What they have done well is aggressive counterterrorism operations. Brian talked about that earlier. They are aggressively pursuing leads they have. Some include kicking in doors and taking people down in the way that they did in dagestan. That is a preemptive counterterrorism strike to secure the games. Internationally, the intelligence is never as good as I've seen it -- or is as good as I've seen it. Excuse me. The Brits are working with the French are working with the United States and everyone in between to try to find those pieces of intelligence that might help protect the games. The one last weakness, and the tension between Russia and the United States is internal sharing of intelligence that we believe would be important. You know, a few weeks ago we saw those reports about the so-called black widow suicide bombers. Those women have not been found. How big a threat is that now to those games or outside those games? Well, you have to take them at face value. They have had successful events. They blew up a train station and two buses in the months leading up to the event. We know there are individuals who fit those descriptions who have the capability to pull off the event. That's what makes it so serious and dangerous. It is something that they're looking for, they're trying to use every piece of intelligence they have external to Russia. They're going on their own internal to Russia. And we can only hope that they'll find those individuals before they're able to penetrate any of the rings. And I don't believe that the terrorists think they have to have a venue event -- a terrorist attack on a particular venue. They just have to have some disruptive event somewhere. That's what makes them more dangerous than the folks who believe they have to have a big event at a venue. I think we heard the head of the national counterterrorism center, Matt Olson, said there is substantial potential for a terrorist attack outside the venue of the olympics. Is that where you're focusing? Clearly. And, again, I think there were, you know -- again, lots of physical presence there. And I think they're going to try to find the weakest point they can find. It may be outside one of those rings of security. That's obviously our concern. It's the softest part of the security -- security part. And just quickly here, if there is an incident, do you believe the United States is prepared to evacuate the athletes? I think all the preparation that can be done to protect our athletes from a United States perspective is there. And it's exceptionally well done. So I believe if there is any event that would lead to the evacuation of our athletes, that, in fact, would happen and would happen orderly and in good order. Again, we are hoping that the Russians would share more internal information on security threats, so the operation in dagestan is a great example. That had some nexus to the games. It would have been helpful if we had a full and robust relationship to share the information to compare to information we get from all of our intelligence partners around the world. Clearly that's important. Thanks, congressman Rogers.
