UN officials say they are gathering testimony from Syrian refugees fleeing into Turkey to escape ongoing unrest in their country.
More than 8,500 people have now crossed the border, as the Syrian army continues to try to stamp out anti-government demonstrations.
For those in Syria struggling to make it to Turkey, conditions are terrible.
One woman in a makeshift camp said: “There are 20 people here in this tent. No food, no water, even nothing to wear. Look at us, we’re suffering. The kids are under the rain, nobody cares about us. Neither the Syrian president nor the Turkish president. Nobody. We are human beings!”
Refugees who have made it to Turkey refute military claims that protesters have killed soldiers and police. They maintain there was a mutiny among the security forces, with the army killing officers who tried to protect civilians.
One man said: “The army of Egypt and the army of Tunisia protect the people. But the army of Syria kills people. They take sides with Bashar Assad and the system.”
The Syrian army is said to be on the move towards another northern town, Maarat al-Numaan, after retaking the flashpoint town of Jisr al-Shughour.
Syrian rights groups say at least 1,300 civilians have been killed since the start of the popular uprising in March.
