As many as 11,000 Syrians have fled the violence in their country in the last 24 hours.
Fresh clashes broke out in the al-Hasakah province in the northeast of Syria between opposition fighters and regime forces battling for control, forcing residents to make a dash for the border into Turkey.
Around 9,000 fled into Turkey, while 1,000 escaped to Lebanon and another 1,000 to Jordan.
It brings the total number of Syrian refugees in the region to 408,000.
Panos Moumtzis, UNHCR Regional Coordinator for Syrian Refugees described the surge in the number of refugees:
“This is the highest number we have received so far and I would say that the arrival of the last 24 hours is really one of the highest we have had for quite some time”
Refugees waited in the Turkish town of Ceylanpinar to be taken to camps.
The International Red Cross has said it is struggling to cope with the huge number of refugees as the conflict in Syria worsens.
