Reporter carol, were just arriving at the mosque right now. Law enforcement officers put up gates to keep people back. Seeing a crush of emergency vehicles including a number of ambulances. What were being told from Fire Department and the Police Department is that at least ten envelopes were found, white powder discovered in the envelopes. It is not at all clear ha that powder is or whether that powder poses a threat. But a spokesperson for the Police Department and the Fire Department are both saying that, as many as 11 people may have come into contact with the substance, so they are taking precautions, having all of the people checked out by medical professionals now. It will take some time, however to determine just what that powder was. We know the testing has started but could take hours, possibly as many as eight. There may not be an an answer until later tonight in belgium. But a city that has been under the highest Terror Threat level for days now. Partial lockdown that people were living under only lifted yesterday when schools began to open and the metro began to open but people are certainly aware of the threat level here, they are feeling the urgency in this case and obviously Law Enforcement, police, fire units want to respond quickly and swiftly, trying to take every precaution, figuring out what the substance is and whether or not its threatening. Ive got to ask you a question you may not know the answer to, but are such threats unusual when it comes to the citys mosques . Reporter not entirely clear to us, carol. I think, at this point, any threat would naturally be taken more seriously, given the climate. What i can tell you, this is a prominent mosque in this city. Its a large mosque. Its a very old mosque and certainly integral part of the community. So, it is a mosque that would draw attention and some focus, one might assume, and certainly being taken seriously now. Im doing a lap around the mosque since we tried to get a live picture up. Its ringed by emergency vehicles. You know that Law Enforcement here is taking this very seriously. And that certainly would be accelerated by the nature and the climate these last few days in brussels. So unless you run around the mosque and get good reporting for us, alexandria field live from brussels. With me cnn contributor and Senior Editor for the daily beast, michael weiss, coauthor of isis inside the arm of terror, hi michael. How are you doing . What do you make of this . Honestly, we dont know. This just happened. You know, the correspondent said brussels has been on lockdown three, four, days high ert terror alert warning. This could be something picked up in the counterterrorism dragnet, or lets not forget a lot of nut jobs like to exploit anxiety, fear, high tension moments. Might have just sent some stuff to the mosque. After 9 11 a huge anthrax scare, particularly new york, washington, d. C. , white powder started turning up at newsrooms and government buildings and so on. You cant discount the fact it could be people who are essentially capitalizing on a very, very, you know, fearful news cycle. All right. Michael weiss, thanks so much. Minutes ago, this just in to cnn, too, turkeys president ratchets up tension over his countrys shootdown of a russian warplane. He sat down foreign exclusive interview with cnn and said turkey will not apologize. This is the u. S. And allies urge both countries to calm the rhetoric. Cnns Becky Anderson in turkey. More on her interview with the turkish president. Good morning. Reporter good morning. This is exactly what he said, ill quote you, i think if there is a party that needs to apologize it is not us, it is those who violated our air space, those are the ones who need to apologize, pilots and armed forces fulfilled duties which consisted to responding to violations of the rules of engagement. I think is is the president , the president told me in an exclusive interview i just finished and got back to this live position to speak to you. He also, once again, reiterated what the turkish Authorities Say were the circumstances of the downing of this jet. Despite the fact that we have had the navigator, the copilot of the downed jet, speaking to russian media, saying there were never warnings, cannot believe this happened, they never violated turkish air space. The president repeating to me, once again, that there were two planes, one entered turkish air space for as long as 17 seconds, the plane was warned ten times, and at that point, when it continued on into the turkish air space the rule of engagement dictated that air space should be defended and they shot the plane down. And despite the fact, carol, this situation risk escalating, calls not least from the u. S. President , nato, from angela merkel, leaders around the world to deescalate the situation, words echoed by the president of turkey, he stood defiant today in this interview when i asked him to respond, for example to what the foreign minister Sergei Lavrov said, he said thises and a planned provocation. Effectively he said nonsense. I put it to him president putin says hes been stabbed in the back and accused turkey of being an accomplice of terror. He was outraged by that comment. Outraged by the fact that the russian Prime Minister had the supply chain on isis oil coming from syrian facilities, outraged, the suggestion of that as well. We had, despite the fact that you have a president here who clearly wants to, and is mindful of the fact, that theres fiery rhetoric from russia isnt going to be useful going forward, this isnt a man who in the face of criticism. He will speak to president putin on sunday in paris perhaps all right. Back to you. All right. Im sorry for our technical difficulties. But of course, as you might expect, its difficult to get a shot live out of turkey these days. We get your point. Turkeys president talking tough. Against that backdrop, just a couple of hours, frances president will sit down with the russian president Vladimir Putin in moscow. Francois hollande will call on the russian president to join a united front against isis rather than go it alone. Its a mission made all of the tougher given russias rising tensions with turkey. Turkeys a nato ally, keep in mind. Jill dougher any moscow, where shes served as cnns bureau chief. Whats the word from moscow. Reporter one way russia can show displeasure of turkey shooting down the su24 is economically. And the economic relationship between turkey and russia is very significant to the total of 44 billion in trade and services. Russia says its going to tighten controls over the import of food from turkey. That totals alone 1. 7 billion. It includes vegetables, fruits, meat, et cetera, coming from turkey. The russians are not saying that it is directly linked to that shootdown, but they are saying its a safety and security measure, that 15 of the imports from turkey dont meet russian standards. Whether thats the case or not, there are also hinting there may be other steps. Certainly tourism is one of them. There are 3. 3 million russian tourists who go to turkey every year. That would be a significant hit to the turkish economy. Also, theyre saying there are other products, childrens clothing, cleaning products, et cetera, that they have concerns about. Now, at the same time, in connection with syria, you have the visit of the french president hollande to russia, meeting with president putin. Now president hollande is talking about creating some type of grand coalition to fight isis, that is his mission here to talk to president putin, to see even in this situation, whether they could work more closely. The situation, of course, is complicated by the shootdown by turkey, and also by a longerterm question, the difference between france and russia on the fate of president assad. But the hope is that somehow, in spite of all of these complex challenges they can Work Together more closely to attack isis. Well see. Jill dougherty, reporting this morning. In syria, isis operative suspected in the beirut terrorist attacks has reportedly been killeden in ambush. The man believed to have transported two suicide bombers who killed 43 people in beirut one day befoparis attacks. The Prime Minister, David Cameron, now wants his country to conduct air strikes directly against isis targets in syria. He went before his Parliament Today, to argue that britain security depends on taking the fight to terrorists in their syrian strongholds. We shouldnt be content with outsourcing our security to our allies. If we believe that action can help protect us, with our allies, we should be part of that action, not standing aside from it. And from this moral point, comes a fundamental question. If we wont act now, when our friend and ally, france, has been struck in this way, our allies in the world can be forgiven for asking, if not now, when . Cameron says he will not call for a vote on air strikes in syria until he is sure it will pass.
