BEIRUT—An airstrike on a rebel training camp in northwestern Syria on Monday killed more than 50 Turkish-backed extremists and wounded nearly as many, a Syrian opposition spokesman and a war monitor said.
The airstrike in the northwestern part of Idlib province, the last rebel enclave in Syria, targeted a military training camp for Failaq al-Sham, one of the largest Turkish-backed opposition groups in Syria, said Youssef Hammoud, a spokesman for the groups.
