they will be negotiating next month in kazakhstan to find a solution to this almost six-year civil war that killed hundreds of thousands of people. another thing to note, too, which is important, is the turks right now are fighting isis in al bar. this is a city that is 30 kilometers from aleppo where the syrian government has forces and the russians are there, as well. this cease fire, this mechanism could be a way that when those two sides the turks and syrian forces are looking across at each other there isn't any sort of conflict between the two sides. there's a lot of moving parts. still early but it is holding. >> all right. ian lee reporting there live on a complex fluid situation. thank you so much. of course he will continue to monitor the cease fire as we try to find out whether we may or may not be at a turning noint the syrian civil war.
