Later, the official said a dozen wounded Syrians had been brought across the border, and one died during treatment. Rumors swirled about the situation in the Syrian town; the Turkish official cited contacts in Ras al-Ayn as saying Syrian forces had entered the town.
A convoy of seven white jeeps and a truck was seen near the Syrian town, but it was unclear who was in the vehicles. On the Turkish side of the border, Turkish jets were heard flying overhead.
At one point, sounds of jubilation were heard coming from Ras al-Ayn. One rebel shouted in Arabic: "The Syrian army fled, did you see?"
The Syrian Observatory for Human Rights said Wednesday that warplanes carried out six airstrikes in al-Hasaka, including those at Ras al-Ayn.
Regime jet fighters also targeted the rebellious suburbs of Damascus on Wednesday, the Britain-based Observatory said. Heavy clashes between rebel units and Assad's troops were ongoing in the northern city of Aleppo, the Observatory said. The group relies on reports from activists on the ground.
