Three Turkish soldiers were accidentally killed and 11 wounded on Thursday when a Russian war plane struck a building in Syria where the troops were deployed, the Turkish army said.
The plane had been seeking to hit targets of Islamic State (IS) militants but "by accident three of our soldiers were martyred when a building was bombed where our units were," it said.
The army said Russian President Vladimir Putin had already reached out to Turkish counterpart Recep Tayyip Erdogan to express his "sadness and condolences."
