Syrian forces swept into border towns Sunday to prevent people from fleeing, as Turkey extended aid to refugees. Syrian forces near the border reportedly attacked those who tried to flee while burning down houses and arresting dozens. It is the first time Turkish authorities, who have already sheltered more than 10,000 Syrian refugees in tent cities on Turkish territory, have launched cross-border aid. Many come from Jisr al-Shughur, the site of the latest crackdown by Syrian troops. Turkish Foreign Minister Ahmet Davutoglu said his country would keep its borders open to Syrians fleeing the violence.
