Syrians are continuing to flock across the border into Turkey as fears grow that Damascus is preparing a major offensive against pro-democracy demonstrators.
More than 2000 people are said to have sought refuge in Red Crescent camps.
Syrians are bracing for more violent protests against the rule of President Bashir al-Assad today, the traditional day of prayer.
Many of the latest refugees have come from Jisr al-Shughour, where authorities claim armed gangs killed 120 security personnel during protests earlier this week.
Locals say the dead were gunned down by fellow soldiers when they refused to open fire on those taking part in the protests.
Now residents say tanks and troops have been deployed around the town ready for a massive crackdown.
