The bombardment hit the northern town of Al-Bab and the nearby area of Tadif, both held by IS, yesterday, the Syrian Observatory for Human Rights said.
Al-Bab has come under heavy assault in recent weeks, with Turkish, Russian and Syrian warplanes carrying out strikes in or around the town.
The Observatory says it determines whose planes carry out raids according to their type, location, flight patterns and the munitions involved.
But Turkish officials insist the utmost is done to avoid any civilian casualties and have vehemently denied claims civilians have been killed in previous strikes.
