are trying to do is trying to figure out how to best cooperate to stop the flow of refugees from turkey into greece. of course there are still thousands of refugees that leave turkey to go to greece every day to make that crossing in these very makeshift boats. here, this is one of the main launching pads in turkey for refugees to find smugglers that will smuggle them out of the country. and one of the more ironic things that this is just a couple of miles away from a part of the city in which you can find dozens of smugglers, hundreds of refugees, most of them syrians, they have this trade that is going on, that will be very hard for the turks to stop. so those talks are going to try to solidify the cooperation to ensure that what was agreed upon yesterday in brussels can actually be implemented and

implemented with the cooperation of both countries, and can start as soon as possible. >> a key driver behind the resettlement plan, which is already attracting some controversy, the idea behind that is to deter refugees from making the journey in the first place, but i guess that's not likely to be the case? >> reporter: oh, absolutely. you are absolutely right. you speak to refugees here. they say that they do not intend to have their journey impeded; that as long as they have the money to pay the smugglers, they will attempt to reach greece. many of the refugees that we have heard from, have said, in fact, that they don't believe that the turks can really get this plan in action soon enough to stop the flow from happening any time soon, that they intend

to continue along this journey. but this is a priority for the turks and the greeks right now, and it will be interesting to see how quickly they can try to implement more cooperation in really trying to lockdown these coasts and try to ensure that the refugees don't continue trying to make that crossing. >> mohammed jamjoom, thank you. ♪ a spokesperson for the u.n. special envoy to syria says talks with the syrian government and opposition will begin no later than monday in geneva. meanwhile the syrian army has recapture advil a village south of aleppo. meanwhile, government officials say at least three
