ANKARA, Turkey (AP/AFP) - An official says a Turkish teenager was killed and two other people were wounded in a town near Syria's border from stray bullets fired during renewed clashes between Syrian rebels and Kurdish gunmen.

The official said on Wednesday Syrian rebels and fighters from the Kurdish Democratic Union Party have resumed battles with the rebel forces in the Syrian town of Ras al-Ain after a six-month lull.

He said the 17-year-old boy was killed in the town of Ceylanpinar on Tuesday. The official from the mayor's office spoke on condition of anonymity because of government rules on speaking to the media.

More than a dozen Ceylanpinar residents have been wounded from stray fire as the two groups battle for control of Ras al-Ain.

Kurdish fighters have expelled jihadists from Ras al-Ain, a watchdog said on Wednesday, adding that only the border crossing remains under the extremists' control.

Kurdish fighters "have taken near-total control of Ras al-Ain after fierce battles raged since (Tuesday) evening, pitting (Kurds) against Al-Nusra Front, the Islamic State of Iraq and Syria and other groups", said the Syrian Observatory for Human Rights.

Ras al-Ain is home to a majority Kurdish population and is of strategic importance given its location close to Turkey.

Its fighters are trying to ensure neither the regime of President Bashar al-Assad nor the opposition takes control of its areas.

The clashes between Kurdish fighters and jihadists broke out after Al-Nusra Front attacked a convoy of Kurdish women fighters, said Observatory director Rami Abdel Rahman.

Nine jihadists and two Kurdish fighters have been killed since battles erupted in Ras al-Ain on Tuesday, said the Observatory.

Activists in Ras al-Ain said members of the jihadist groups had taken advantage of the Muslim fasting month of Ramadan, which began last week, to try to impose their extreme version of Islam.

In the early days of the Syrian conflict, when opponents of the Assad regime were desperate for assistance from any quarter, jihadist fighters were welcomed but a spate of abuses has fuelled a major backlash.
