Iran has strongly condemned Israel's "frequent aggression against Syria's infrastructure and its occupation of other parts of the Golan," according to a statement by Foreign Ministry Spokesperson Esmaeil Baghaei on Monday night.

The statement was released in response to Israeli airstrikes over the past two days targeting former Syrian government military and security sites in different parts of Syria as well as Israel's seizure of the Syrian buffer zone in the Golan Heights and neighboring lands.

Baghaei criticized Western states for supporting Israel with their "silence and inaction" in the face of Israel's "flagrant lawbreaking."

He added Israel's military attacks on the Syrian territory under current circumstances were a clear violation of the United Nations Charter, and called on the UN Security Council to take immediate action to stop the Israeli "aggression" and hold it to account.

Syrian rebel forces took the capital Damascus and declared the collapse of Assad's government on Sunday.

Israeli warplanes on Sunday and Monday hit military and security sites in and around Damascus, the southwestern province of Quneitra, Syrian navy vessels at Latakia Port, and military depots in coastal areas.

In addition, the Israeli military crossed into the demilitarized buffer zone established under the 1974 ceasefire agreement between Israel and Syria, taking control of border areas as of Monday, according to Syrian and Israeli sources.
