The fighting in Syria has been going on for 22 months now, and it's not just the death toll which keeps rising.
Increasing too is the number of Syrians forced to flee to refugee camps like this one in the northern town of Atme, 60km from Idlib.
Conditions in the camp, which houses between 15-20 thousand refugees, are difficult, particularly in the winter months.
This refugee says the numbers in the camp increase day by day.
He says this is a result of the continued violent attacks by the regime against the Syrian people.
The conflict in Syria has so far claimed over 60,000 lives, according to UN statistics.
