We struck Iranian targets in Syria after missile fire: Israel

Jerusalem: Israel struck what it said were Iranian targets in Syria early Monday in response to missile fire it blamed on Iran, sparking concerns of an escalation after a monitor reported 11 fighters killed.

Israel announced the strikes against facilities it said belonged to the Iranian Revolutionary Guards' Quds Force as they were occurring, continuing its recent practice of speaking more openly about such raids.

It said the strikes were in response to a medium-range, surface-to-surface missile the Quds Force fired from Syria at the Israeli-occupied Golan Heights on Sunday, which Israeli air defences intercepted.

"We saw that as an unacceptable attack by the Iranian troops - not proxies, not Shiite militias, not Syrian forces - Iranian troops firing an Iranian-made missile from the vicinity of Damascus towards sovereign Israel," Israeli military spokesman Jonathan Conricus told journalists.

Israel said targets included munitions stores, a site at Damascus International Airport that was allegedly the Quds Force's main logistics hub in the country, an Iranian intelligence installation and an Iranian military training camp.

It said it also hit Syrian air defence batteries in response to dozens of missiles fired from them.

The Syrian Observatory for Human Rights war monitor said at least 11 pro-regime fighters including two Syrians were killed.

Russia, which like Iran is a key backer of Syrian President Bashar al-Assad in the country's war, said the Israeli strikes killed four Syrian soldiers and wounded six, while damaging Damascus airport infrastructure.

The Observatory said air strikes and ground-to-ground missiles hit targets around the capital including near the Damascus airport, as well as near the Thaala military airport in Sweida province to the south of the capital.

The targets included weapons depots belonging to the Lebanese Shiite movement Hezbollah and Iranian fighters, it added.

The chain of events leading to the strikes began Sunday.

Damascus initially accused Israel of carrying out raids in southern Syria. Syrian state news agency SANA quoted a military source saying Syria's air defences went into action after Israel launched the air strikes.

In those strikes, the Russian army said Syrian air defences had destroyed seven Israeli projectiles, after four of the Jewish state's F-16 military planes "fired rockets into Syrian territory".

Shortly afterward on Sunday afternoon, Israel said it had intercepted what it then called a rocket fired at the Golan Heights from Syria.
