Damascus: Syrian state media said Monday that overnight Israeli strikes killed at least 14 people in central Hama province, raising an earlier toll of five dead and 19 wounded.
Since the start of the civil war in Syria in 2011, Israel has carried out hundreds of strikes there, targeting pro-Iranian groups in particular.
"The number of martyrs resulting from the Israeli aggression on a number of sites in the vicinity of Masyaf has risen to 14 martyrs and 43 wounded including six critically," official news agency SANA reported citing a medical source. A Syrian war monitor earlier reported at least seven dead.
"Thirteen violent explosions rang out in the zone housing scientific research centres in Masyaf where pro-Iranian groups and weapons development experts are present," the group said in an earlier statement.
The Syrian state news agency Sana had previously reported five killed and 19 wounded near Masyaf, citing a medical source.
"Around 11:20 pm (2020 GMT) on Sunday, the Israeli enemy carried out an air attack from the northwest of Lebanon targeting a number of military sites in the central region," Sana reported, citing a military source.
"Our air defence shot down some missiles."
Israeli air raids in Syria have intensified since the October 7 Hamas attack on Israel that sparked the war in Gaza.
Israeli authorities rarely comment on individual strikes in Syria, but have repeatedly said they will not allow arch-enemy Iran to expand its presence there.
At the end of August, three pro-Iranian fighters were killed in the central region of Homs in strikes attributed to Israel, the Observatory said.
A few days later, the Israeli military said it had killed an unspecified number of fighters belonging to Hamas ally Islamic Jihad in a strike in Syria near the Lebanese border.
