KEILAR: New developments in a looming humanitarian crisis. Today, Turkey's border has been reopened, allowing more than 1,000 Syrians to escape across the border as they flee new ISIS fighting. We can see as many as 2,000 come across Turkey just today. 2800 broke across the border on Sunday. As many as 100,000 could flee Tal Abyad, which would add to the staggering 1.8 million Syrian refugees. Our Arwa Damon is at the border.</s>ARWA DAMON, CNN SENIOR INTERNATIONAL CORRESPONDENT: People are understandably upset as they are just being allowed to come across. The women were saying it's beyond a nightmare. We've seen groups of nightmare also dumping water on themselves and it's been fairly difficult and some of them having to wait overnight, women, children, babies, all of them. This is just the latest round of individuals that are fleeing the latest bout of fighting. In this particular case, we are talking about a vital town called Tal Abyad that is under ISIS control. And there are Kurdish fighters in Tal Abyad just out of eyesight on the other side of that wall. They will have cut off one of the key ISIS strategic routes to their stronghold of Raqqa. You can see also the Turkish military is readying themselves along this border. People were in a panic a few days ago that they literally forced down this wall in some areas. And for so many of those coming across, this is not necessarily the first time they have been forced to flee. Some we were talking to who were living in Tal Abyad said they were refugees there as well. They don't want to necessarily live under ISIS but for some of them it was a better option than living in security and having to make the choice and come across and end up as refugees.
