months. they obviously have some syrian militias that are also fighting on their side, mostly trying to take territory away from isis, also fighting with some kurdish factions there as well. and essentially, those areas are now under turkish control, so those could be considered safe zones. but the places that the people that we're seeing in east aleppo are going to certainly are not safe zones. you have places like idlig province, which is a place that's held by the opposition. quite a lot of islamic factions, including some links to al qaeda there as well. the people who are going there are going to be subjected to another war zone. there's bombings going on there, there's air forces, especially the russians and the syrians flying there as well. so, putting in place new safe zones will certainly be difficult, especially in those areas that russia is operating in, but there are already some places that are safe for civilians, but they're not very big, and they certainly don't have the infrastructure to take in the tens of thousands of people who are fleeing their homes right now. >> fred pleitgen, thank you so much for bringing us the latest
