Syria: Refugees flee border camps as troops deploy

Hundreds of Syrian refugees are fleeing across the border into Turkey to escape an assault by Syrian troops in the area, witnesses say.

Tanks and snipers have entered the village of Khirbet al-Jouz, a base for makeshift refugee camps.

One group of people broke through barbed wire to cross the border close to the Turkish village of Guvecci.

More than 1,300 people are estimated to have been killed in the government crackdown on the popular uprising.
