JERUSALEM (AP) — The Israeli military said it struck dozens of Iranian targets in Syria today, carrying out a “wide-scale” strike in response to rocket fire on the Israeli-controlled Golan Heights the day before.

A Britain-based war monitoring group said the Israeli airstrikes killed 11 people, including seven non-Syrians who are most likely Iranians. Syrian state media only reported that two civilians were killed. The Israeli military said its fighter jets hit multiple targets belonging to Iran’s elite Quds force, including surface-to-air missiles, weapons warehouses and military bases. After the Syrian military fired an air defense missile, the Israeli military said a number of Syrian aerial defense batteries were also destroyed.

The death toll of 11 was reported by Rami Abdurrahman, who heads the Britain-based Syrian Observatory for Human Rights, an opposition activist group with a network of activists across Syria.

The Observatory said the airstrikes targeted arms depots belonging to the Quds Force in the Damascus suburbs of Kisweh and Qudsaya. Abdurrahman added that several other areas were targeted in today’s strikes, including the Mazzeh airbase in western Damascus where air defense units are stationed.

Syria’s state SANA news agency said the two civilians were killed by shrapnel when an Israeli missile hit a house in the town of Saasaa, southwest of Damascus. It said several others were wounded, including a girl in a residential building in the suburb of Qudsaya, also west of the Syrian capital.

It claimed that Syrian air defenses destroyed most of the Israeli missiles before they reached their targets.

Today’s strikes on Syria were the most intense since Jan. 21, when Israel claimed responsibility for a series of airstrikes on Iranian military targets in the Arab country, including munition storage facilities, an intelligence site and a military training camp, in response to an Iranian missile attack the previous day.

Israel had said the missile, fired by Iranian forces in Syria, was intercepted over a ski resort on the Golan Heights and that there were no injuries. The Iranian launch followed a rare Israeli daylight air raid near the Damascus International Airport.

The latest strikes further burst into the open what’s been a long shadow war between Israel and its archenemy Iran. The two foes have increasingly clashed over what Israel says is Iran’s deeper presence along its borders.

“Yesterday’s Iranian attack towards Israel is further clear proof of the purpose of the Iranian entrenchment in Syria, which threatens Israeli security, regional stability and the Syrian regime,” the military said in a statement.
