Syria's state-run news agency reported that at least 14 people were killed in several airstrikes believed to have been carried out by Israel on targets across Syria.
Five locations, including a science research center, were reportedly targeted.
Israel does not usually comment on attacks in Syria and has not responded to this one.
A British war watchdog said the attacks followed a series of attacks, targeting military facilities in the city of Masyaf where Iranian-backed weapons development experts work.
