An air strike
killed more than 40 members of the jihadist group Jabhat Fateh al-Sham
in northwestern Syria on Thursday night, the Syrian Observatory for
Human Rights said.
The group, formerly known as the Nusra Front, could not immediately be reached for comment.
Observatory said the air strike had targeted a Fateh al-Sham base in a
rebel-held area west of Aleppo, and it was not clear if it had been
carried out by Russian or U.S. planes. The Nusra Front renamed itself
Fateh al-Sham last year when it formally dissolved ties to al Qaeda.
