The Red Crescent says 2.5m people have been displaced by Syria's civil war.
According to the UN, on one day this month 11,0000 people fled to neighbouring countries - but many are not able to escape Syria.
The BBC's Paul Wood went to the camp at Atma in the north of the country on the Turkish border.
One Syrian woman in the camp told him: "The whole world knows what's happening here. Did we get any help? No toilets, no water, no food. We can't even get clean enough to pray."
Senior cleric Samir Ibrahim, from the Mosque within the camp, said: "We hope the UN and countries like Britain hurry up and support the Syrian people. The more they wait, the more radicalism will breed and the more extreme organisations will emerge."
