Activists say that Syrian government airstrikes have killed nearly 50 people in a rebel-held city this week.

The Britain-based Syrian Observatory for Human Rights said Wednesday that it counted 48 killed in two days of strikes on the city of Talbiseh. The Observatory said the bombing occurred on Monday and Tuesday.

The death toll is unusually high, even by the vicious standards of the Syrian civil war.

Similar information was reported by a local Talbiseh activist collective.

The Observatory said that leading members of a rebel group were killed, but didn't identify which one. The bombings also crushed families under rubble, both groups reported.

State-run media said Tuesday that the army targeted a meeting of "terrorists."

Syrian officials refer to armed rebels as "terrorists."
