Moscow on Wednesday said Israel had violated Syria's sovereignty with airstrikes the day before, after Israel and Damascus blamed each other for the hostilities.

"We are very concerned by the attacks and how they were made. This is a gross violation of the sovereignty of Syria," the Russian ministry of foreign affairs said in a statement.

Moscow's defense ministry earlier said Israeli strikes had endangered two passenger planes.

"The provocative actions of the Israeli air force.. directly threatened two airliners," ministry spokesman Igor Konashenkov said in a statement.

He said the attack came from over Lebanese territory and came as "two airliners, not from Russia, were preparing to land at the airports of Beirut and Damascus".

He said restrictions were imposed on the use of Syrian government forces' air defense systems "to prevent a tragedy". One of the planes was redirected to a Russian airbase within Syria.

The Russian defense ministry said three Syrian military personnel were injured in a strike that saw Israeli warplanes drop 16 bombs.

The targets of the Israeli air strikes were several Hezbollah leaders, according to a report by Newsweek. The airstrike was conducted minutes after the leaders boarded a plane bound for Iran, according to the report.

Several Iranian ammunition supply points were also a target of the bombing, the source said. The supply points contained valuable, GPS-guided ammunition from 2017, some of the best available to the Iranian army and Hezbollah.

Israel has not confirmed or denied that it is behind the airstrike.
