UNICEF Executive Director, Peter Power, says the aftermath of the quakes is devastating.
"Our teams on the ground, in both Aleppo, Gaziantep and other areas, are sending through some frankly, harrowing reports about what they're finding and what they're seeing, especially in the more remote areas.
"The level of destruction is huge and it's widespread.
"Some towns have been completely obliterated and millions of people are without shelter or food."
