Israeli warplanes struck a Syrian military outpost near Damascus. Most of the structures appear to be barracks and garages.
"Israeli planes targeted the Jamraya region near Damascus, including a scientific research center and warehouses where weapons and ammunition of the regime and its allies were stocked", Rami Abdurrahman, the director of the Britain-based SOHR, told the AFP news agency.
With details still emerging on Israel's Friday attack against a military site south of the Syrian capital city of Damascus, a strike which Israeli media have presented as being an attack against Iran, a new round of strikes was reported Monday night, against different targets in metro Damascus.
"The Syrian defenses confronted the aircraft in the area, as the area itself had been subjected to Israeli raids more than once", the report in Al-Mayadeen added.
There was no official Israeli comment.
The military source said Syrian air defence systems intercepted three of the missiles.
If true, this would be the first reported operational use of the Jericho 1 ballistic missile.
Netanyahu has repeatedly stated that Tel Aviv is free to act in Syria for the sake of its security, while Damascus regards any foreign states' military actions in the country without Damascus' "aggression".
Images of the base broadcast by the BBC showed "a series of two dozen large low-rise buildings, likely for housing soldiers and vehicles".
According to the Israeli military analysis blog Intelli Times, the transport jeeps and trucks with attached rocket launchers seen in the footage were consistent with the types used by Iran-backed Shiite militias.
A few days later, ImageSat International took photographs, also with the EROS-B satellite of the site, which further supported the BBC claim. "I sent it because he had indicated that forces under his control might in fact threaten US interests in Iraq", the CIA chief said.
Israel has long viewed Iran as its enemy number one.
He said that Iran maintained a "legitimate" presence in Syria, according to the Interfax news agency. I don't want to tell you by the year or by the month.
