Istanbul (dpa) - A mortar shell fired from neighbouring Syria landed in a school yard in southern Turkey, killing one person and injuring three, the governor of Kilis province said.
The person killed was a school employee. Other mortars landed in an open field nearby.
A video clip from the school showed parents escorting frightened, crying children away from the scene.
Heavy fighting is taking place just over the border inside Syria between Islamic State militants and rebels factions that include those backed by Turkey, according to the Syrian Observatory for Human Rights, a monitoring group.
Turkey launched artillery shells at Islamic State positions just over the border, the monitor said.
Ankara has been concerned the Islamic State extremist group could gain control over a key road just near the frontlines that connects the rebel-held city of Aleppo with Turkey.
Syria's multi-sided civil war between President Bashar al-Assad's regime, Kurdish forces, armed rebel groups and Islamic State extremists has spilled over the border into Turkey on a number of occasions.
