 In the middle east country of Syria, most people who live there in 2011 have had to move. Some stayed in Syria, others have sought refuge in places like Europe. The UN estimated that more than 250,000 people have been killed in Syria's civil war. Over the weekend, the UN opened peace talks with some different groups involved. But it suspended those talk yesterday saying there had not been much progress. The organization plans to try again later this month. International involvement in Syria is complicated. The US continues its attack on the ISIS terrorist group. But it also wants Syria's president out of power, and is supporting some of the rival fighting him. But Russia is backing Syria's president, and though Russia says it's attacking Syrian terrorist group, the US accused it of also targeting any enemies of Syria's president, sometimes killing civilians, and some of the rivals that US supports. One thing is certain. There is no end insight to the war. This place does not exist, according to the US Defense Department, but behind that birm and freshly dug earth, a small agricultural air strip has been turned into something very different. A military airfield just 100 miles from ISIS position. Satellite photos show the work that has been down here in recent months. So you can see behind me, they are working to extend the runway, so that larger planes could land here. The advantage of this site is that it is well secured inside Kurdish territory so it could be used to supply US special forces deployed here in Syria. He is coming now. We were escorted away from the airfield as soon as we were spotted. He told it was a military zone. It is another example of the US's growing military footprint in this remote corner of northern Syria. And it is deepening relationship with Syrian Kurdish fighters, known as the YPG. In an abandoned apartment building closer to the front line, we were given access to the YPG's joint operations room. It is a modest setup. 21 year old D and his colleages talks to their men on battlefield. Using newly provided tablet, they pass on enemy locations to a coalition command center from where air strikes can be launched. Right now, this is the frontline of H, he says, our comrades there have seen the movement of two enemy fighters, and so we send this message along with their coordinates to the general commander's room. When there are heavy clashes, the operation's room move to the front line. Who taught you how to use this? He tells us, a group of foreigners and Americans trained his commanders, who in turn trained him and his comrades. In the sky and armed ground in Syria, the US is deepening its commitment to the battle against ISIS.
