Russia expressed "serious concern" to "Israel's" ambassador on Wednesday about air strikes that shut down Syria's Damascus International Airport last week, according to the foreign ministry.

Syria has been a Russian ally since Russia aided the country in its fight against terrorism. Following the Israeli strikes, Syria halted flights to and from the airport until further notice.

"Serious concern was again expressed over the June 10 Israeli air force attack on the civilian airport of Damascus, which damaged the runway, navigation equipment, and buildings, and disrupted international civilian air traffic," the ministry said after Deputy Foreign Minister Mikhail Bogdanov met Israeli Ambassador Alexander Ben Zvi in Moscow.

"The ambassador was told that the justification received from the Israeli side regarding the strike ... was unconvincing and that Moscow expected additional clarification."

"Israel," condemned the Russian military operation in Ukraine as "a serious violation of international order" and has since remained largely muted on Moscow's actions.

"The Syrian air defenses are responding to hostile targeted in the airspace of Souther Damascus," the Syrian Arab News Agency (SANA) had reported at the time the attack was going on.

This is the first aggression launched by the Israeli occupation on Syria in June, with successive aggression conducted throughout May, the latest of which was reported as launched in the Southern countryside of Damascus on May 21.
