Syria air strike kills 22 militants linked to al Qaida

At least 22 militants have been killed in an air strike on an al Qaida-affiliated headquarters in northern Syria, a monitoring group has said.

The Britain-based Syrian Observatory for Human Rights said jets thought to belong to the Syrian or Russian air forces targeted the headquarters of Jund al-Aqsa, an extremist group that fights alongside the Nusra Front, al Qaida's affiliate in Syria, on Sunday night.
