BEIRUT - A Syrian teacher was killed and 23 students were wounded when a mortar shell hit their school on Wednesday in the heart of Damascus, Syrian state media said.
The Syrian Observatory for Human Rights, which tracks violence in the country, said two mortars hit the school and that most of the wounded were in critical condition.
State media said "terrorists" had carried out the attack, a term it uses to describe insurgents.
No group has so far claimed responsibility for the attack.
Damascus has largely been shielded from the war which has killed more than 220,000 since a revolt against President Bashar al-Assad erupted in 2011.
