Finding faith. ♪ A new generation of evangelicals stepping up, but is their political power on the decline? A special Easter Sunday conversation with franklin graham. Plus, baby on board. We have our first child arriving later this year. Chelsea Clinton's surprise announcement. Has a Clinton dynasty begun? From ABC news, "This week" with George stephanopoulos begins now. Good morning, I'm Martha Raddatz, happy Easter. As we come on the air this morning, we have three stories which could affect your safety and security breaking right now. In Boston, an unprecedented operation unfolding to protect tomorrow's marathon. In Yemen, where a U.S. Drone just took out ten suspected Al Qaeda militants, was it in response to this new terror video? And Ukraine, where civil war looks increasingly likely after a fragile truce destroyed moments ago by a checkpoint firefight. We have team coverage from around the globe. We do begin with Alex marquadt in Ukraine. Alex? Reporter: Good morning, Martha. A mysterious and deadly shootout this morning. Is deepening divisions and raising tensions here after Ukraine had announced an Easter suspension of its military operation to squash pro-russia unrest in the eastern part of the country. Around 3:00 A.M., pro-russian militants say they were attacked and say several of their members were killed. By a far-right nationalist group. Now, the evidence they're offering is suspicious, but already Moscow is saying, they're outraged by Ukraine's unwillingness to control anti-russian extremists. The latest sign from the deal signed last week has had no effect. Leave occupied buildings like this one here. But so far no one has budged. Martha. Thanks, Alex. Now to that big hit against Al Qaeda in Yemen. A U.S. Drone taking out ten of the terror group's suspected operatives. Let's go straight to one of the only west earn journalists inside Yemen, reporter iona Craig, she joins us on the phone. Thanks for joining us. Tell us what you know about these militants. Yes, we don't know the names or ranks of those members. The government has said that they were apparently involved in organizing operations against the military and security installations here in Yemen. But it's obviously difficult to independently verify those claims. But certainly, even the government has acknowledged three civilians were also killed in that strike. And you're hearing this morning, there were also more air strikes in Yemen? Yes, there were at least one if not two more strikes this morning. The military defense this morning has described those as air strikes. They were carried out in an area which has been regularly targeted by the Yemeni air force here. All in some sort of area of southern Yemen, which has become a real stronghold. There was an Al Qaeda terror tape released recently, any tie-in between that tape and these strikes? It's very unclear. It was hit very soon after that video was released. That certainly indicated that area was being targeted perhaps as a result of that video being released. Our thanks to iona. Let's bring in Michael Mccaul. From the house homeland security committee. I want to talk to chairman Mccaul, first, you have been briefed on this, what do you know? Well, if the reporting's accurate, this is a very significant drone strike. As you know, Al Qaeda in the Arabian peninsula, poses probably the greatest external threat to the homeland itself. They are the ones who are involve with bombmaking devices to go undetected on airplanes, they're the ones who create and inspired magazine that inspired Boston bombers. The fact of the administration is going aggressively against these terrorists is a very positive sign, given the prior narrative that Al Qaeda is on the run and this is all over. I do view it as the most lethal force, if you will, opposing the greatest external threat to the U.S. In that tape we saw, it was taken in broad daylight, and you had an Al Qaeda leader, what does that tell you about what they're thinking? Well, either they're brazen or not very smart, over the last 12 years, we have maintained a focus on those individuals who pose threats not only to our people but our partners and we'll pursue them wherever they may be, to provide additional intelligence to help us locate them, is not very smart on their behalf. And some of those in the tape had blurred faces, the Al Qaeda operatives blurred the faces in the tape, what does that tell you? That tells you, they don't want you to know who they're. They are. I don't know. There are a lot of different players involved in this and we're working closely with our partners, so there are a lot of folks who maintain this pressure and anything we need to protect in terms of tactics, techniques, procedures or certain individuals that we don't want to disclose. Is at play here. Okay, thanks to both of you.
