Weather conditions are only making matters worse for the thousands left homeless in Turkey after a 7.2-magnitude quake hit Turkey four days ago.

The death toll from the quite has soared to 523. Operation Blessing International is in the heart of the earthquake zone.

"Hopes are fading fast for survivors because it is so cold here," Operation Blessing's David Darg said.

"So now the focus is turning to those who have survived and what we can do for those who are living in camps all over the area," he said.

"There's a camp right outside this building with 175 families living in it. And OB, today, secured two truckloads of supplies for that camp -- a truckload full of bottled water, which is in huge demand here -- and some ready-to-eat meals... and some diapers for the infants," he said.

Other foreign assistance is beginning to arrive. On Wednesday, Israel shipped prefab mobile homes, blankets, and other emergency supplies despite the strained political relationship with Turkey.

A spokesman for the Israeli Ministry of Defense said that Israel will do everything it can to help those who have lost their homes stay warm, safe, and protected.
