Syrians are fleeing a restive northern town and heading into Turkey, ahead of a possible military assault by President Assad’s forces.
Some say they have been attacked during funeral processions. Others fear the worst is to come.
Reports say more than 120 Syrians crossed the border overnight.
Turkish Prime Minister Recep Tayyip Erdogan said his country would not “close its doors” to refugees fleeing unrest in Syria. He has urged Damascus to show more tolerance towards its citizens.
Residents of Jisr al-Shughour are bracing for a backlash over the reported deaths of 120 security personnel there. The regime claims they were killed by armed gangs. Locals and activists say the casualties followed a mutiny among forces sent to quell civilian protests.
Syria’s ambassador in France meanwhile has been denying she has quit over the crackdown. Lamia Chakkour said the reports were part of a campaign of disinformation against Damascus.
