TEHRAN, May 11 (Xinhua) -- Iran's Foreign Ministry on Friday strongly condemned recent Israel's attacks on Syria.

The Foreign Ministry Spokesman Bahram Qasemi said that Israel's strikes on the Syrian territory amounted to an act of aggression, according to the Ministry's official website.

"The Zionist regime's multiple strikes on the Syrian soil and the blatant violation of the country's sovereignty, especially in recent days, were a clear act of aggression," Qasemi said.

Also, "The Zionist regime's constant attacks on Syrian soil, which came under self-made and baseless pretexts, amount to a breach of Syria's national sovereignty and territorial integrity and runs counter to all international rules," he was quoted as saying.

Qasemi criticized what he called "the silence of countries and international institutions in the face of such acts and aggressive behavior by the Zionist regime."

Such aggressions would result in instability and insecurity of the region, he warned.

On Thursday, Israeli fighter jets struck dozens of military targets in Syria in response to a rocket attack on the Israeli-occupied Golan Heights, a statement by the Israeli Defense Forces (IDF) said.

The targets were Iranian military bases in Syria, the statement said, adding that Israel raids were in response to a rocket attack on the Israeli-occupied Golan Heights by Iran's Islamic Revolutionary Guard Corps (IRGC).

Iran has not reacted to the allegations so far.
