The Turkish armed forces attacked a convoy of al-Qaeda-linked rebel vehicles in Syria in retaliation for cross-border fire on Tuesday, destroying three vehicles, Turkish media said.

Turkish troops opened fire on Islamic State of Iraq and the Levant (ISIL) positions in northern Syria after a mortar shell fired from Syria landed in Turkish territory during clashes between ISIL and the Free Syrian Army, broadcaster NTV reported.

It said a pick-up truck, a lorry and a bus were destroyed in the Turkish retaliation on Tuesday evening.

There were no reports of casualties and NTV did not say exactly where along the border the attack occurred.

Turkish newspaper Todays Zaman retracted a report that claimed that Turkish fighter jets had hit the ISIL convoy in northern Syria.

The initial report said that Turkish F-16s had struck a number of ISIL vehicles "after militants opened fire on a military outpost" on the Turkey-Syria border on Wednesday.

NTV did not mention involvement of the Turkish air force.

Turkish media have cited a two-day escalation in hostilities between the sides, but the Turkish military has only retaliated with tanks and artillery fire.
