Istanbul: Turkey's state-run news agency says four people have been injured in an explosion at a school in the city of Kilis, near the border with Syria.
The Anadolu Agency says ambulances took the injured from the Eyup Gokceimam middle school to the public hospital in Kilis.
The mayor of Kilis, Hasan Kara, says the cause of the explosion may have been "two or more mortars" fired from Syria.
Kara told Turkish NTV television no children are injured "as of now" and that the school has been evacuated.
Anadolu didn't cite the cause of the explosion but said there had been material damage to the garden of the school and a car parked in the area.
