Syria's official news agency SANA said the air assaults were carried out on the city of Deir ez-Zor and the town of Bukamal, along the border with Iraq, in the early hours of Wednesday.
SANA, citing a military source, said that Israel launched the air aggression “exactly 01:10 at dawn,” adding that officials were assessing if any damage or casualties were caused.
The US official with knowledge of the attack, who requested anonymity, told The Associated Press that Secretary of State Mike Pompeo had discussed the raid with Yossi Cohen, chief of Israel’s spy agency Mossad, at a public meeting in a Washington restaurant on Monday.
The official claimed the attack hit Iranian-linked targets, alleging the strikes targeted a series of warehouses used to store and stage Iranian weapons, Press TV reported.
Israel has already claimed to have hit Iranian targets and positions in Syria. Iranian officials have vehemently refuted the allegations, stressing that such "lies" will not impede Tehran's advisory assistance to Damascus in its anti-terror fight.
Iran says its presence in the Arab country has always assumed an advisory form, never featuring deployment of servicemen or military units.
