Ankara: Officials say Turkish artillery units have fired into Syrian territory in retaliation for a rocket that hit a mosque in a Turkish border town, injuring a 60-year old Syrian woman refugee.

The governor’s office for Turkey’s Hatay province said on Monday three mortar rounds fired during fighting between the Syrian regime and opposition forces also landed on Turkish territory, but did not hurt anyone.

It said Turkish artillery retaliated by firing at the region the rocket and mortar rounds originated from. Turkey frequently retaliates against stray fire from Syrian government or opposition forces.

Last week, Turkey shot down a Syrian fighter jet which it said violated Turkey’s airspace.
