Israeli warplanes attacked a military base near Latakia, Syria, early on Thursday, an Obama administration official confirmed to CNN.
The planes hit a missile storage site that housed weapons the Israelis feared would be sent to Hezbollah fighters, the official said.
Anonymous sources told Saudi-owned media organization Al-Arabiya that the Israeli Air Force struck sites in Latakia and Damascus, targeting and destroying caches of SA-8 surface-to-air missiles.
The official Lebanese news agency reported that Israeli planes were seen in the skies over south Lebanon on Wednesday.
The Syrian opposition has claimed that Israel attacked missile warehouses near Latakia in July. The New York Times later reported that the attack had only been partially successful, with some missiles having been moved before the strike.
The Israeli government has not confirmed Thursday’s attack.
