A Syrian fighter jet on Monday bombed an area near the Turkish border, causing several casualties, officials and witnesses said.

An Associated Press video journalist saw the plane bomb an area around the Syrian town of Ras al-Ayn, some 10 meters from the Turkish border. Last week the rebels overran three security compounds in the town, located in the predominantly Kurdish oil-producing northeastern province of al-Hasaka, wresting control from the regime forces.

An official at the local mayor’s office said Turkish ambulances were carrying several injured Syrians to a hospital, across the border in the Turkish town of Ceylanpinar. He spoke on condition of anonymity because he was not authorized to speak to reporters.

The force of the blast shattered shop windows in Ceylanpinar, in southeastern Turkey, the official said. It was not clear if anyone in Ceylanpinar was injured in the bombing.

The fighting in Ras al—Ayn touched off a massive flow of refugees two days ago, and more refugees were seen coming after the blast.

Earlier, a Syrian helicopter bombed rebel positions in an area further south of Ras al—Ayn and the rebels could be heard responding with machine guns, the official said.

The violence in Syria has killed more than 36,000 people since an uprising against President Bashar Assad’s regime began in March 2011. Hundreds of thousands have fled the fighting into neighboring Turkey, Jordan, Lebanon and Iraq. Another 11,000 escaped into Turkey on Friday following the surge of fighting at Ras al—Ayn.
