At least 14 civilians have been killed and dozens of others wounded when a rocket attack hit the town of al-Bab in northern Syria.
The opposition’s Syrian Civil Defence, said five children were among those killed and that the number of those wounded was 30.
The attack came days after an air attack killed Syrian troops and United States-backed Kurdish fighters in Aleppo.
The Syrian Observatory for Human Rights said government forces had carried out Friday’s attack and that it was in retaliation for the Turkish raid.
