Operation House of Cards

The May 2018 Israel–Iran clashes were a series of short military confrontations between Israeli and Iranian forces in Syria. On 10 May 2018 the Israeli military stated that Iranian forces in Syria launched 20 rockets against Israeli army positions on Western Golan Heights. Syrian Observatory for Human Rights said that the attack occurred after Baath, a town in the demilitarised zone, was bombarded by Israeli forces. According to the Israel Defense Forces (IDF) some missiles were intercepted by Israel's Iron Dome system, while some fell short in Syrian territory. Following this, Israel launched an extensive strike in Syria against Iranian targets, called Operation House of Cards (, mivtza beit haKlafim) targeting Iranian military bases in Syria. Syria state media called the attacks an act of Israeli aggression on Syrian territories. Iran denied Israeli claims, stating it had neither fired rockets against Israel nor had any military bases in Syria. During the operation, the Israel Air Force destroyed a number of Syrian air defense batteries, including a Pantsir-S1 system, a S-75 Dvina system, a S-200 missile system radar, and a Buk missile system.

The clash came during rising tensions between Israel and Iranian forces in Syria, including threats by the leader of Iran's Quds Force in Syria, Qasem Soleimani, to attack Israel. The incidents also came just a day after the US announced it was withdrawing from the Iranian nuclear deal.

Background
On 10 February 2018, an Israeli F-16I was shot down by the Syrian air defenses after conducting an air raid on Iran-backed positions inside Syrian territory. The aircraft was part of a larger Israeli aerial dispatch which Israel said was sent in response to detection of an Iranian drone entering Israeli airspace. Two hours after the downing of the jet, Israel began attacking additional targets inside Syria, including air defense sites.

On 9 April, Israeli aircraft targeted the T-4 air base in the Syrian province of Homs, killing up to 14 soldiers, including seven Iranians, two days after a reported chemical attack was carried out by the Syrian government.

On 30 April 2018, Israeli Prime Minister Benjamin Netanyahu accused Iran to pursue a program of nuclear weapons development.

On 8 May 2018, U.S. President Donald Trump announced that the U.S. would withdraw from the Joint Comprehensive Plan of Action. The same day Israeli air strikes targeted Syrian army positions in the southern Damascus area of Al-Kiswah, killing 15 people, including 8 Iranians according to the Syrian Observatory for Human Rights. According to reports, the targets were Iranian rocket launchers aimed at Israeli territory.

Events
On 10 May, Iranian forces on the Syrian-held side of the Golan Heights reportedly fired around 20 Fajr-5 rockets towards Israeli army positions, though there were no damage or injuries. Abolfazl Hassanbeigi, Vice Chairman of Iran's Supreme National Security Council denied Iran was behind the rocket attack on Israel, stating that "Teheran has nothing to do with the missiles launched at Israel from Syria overnight Wednesday". According to the Fox News the Iranian missile barrage was done without the notification of the Syrian government. Fares Shehabi, a member of the Syrian Parliament, said that "it was Syria who launched 50 missiles, not 20 as claimed by IDF."

The Israeli army stated that in response, it launched "Operation House of Cards", the "most extensive strike in Syria in decades", attacking dozens of alleged Iranian targets. According to Russia's Defense Ministry, this involved 28 warplanes and the firing of 70 missiles.

The Syrian army command stated that most of the missiles launched by Israel had been intercepted.

According to Israeli sources, the targets hit by Israel, included Iranian intelligence sites operated by the Quds Force.
 * Logistics headquarters of the Quds Force.
 * A military compound and logistics complex of the Quds Force in Kiswah.
 * An Iranian military camp north of Damascus.
 * Weapons storage sites belonging to the Quds Force at Damascus International Airport.
 * Intelligence systems and installations associated with the Quds Force.
 * Observation, military posts and weapons in the buffer zone.
 * In addition, the Iranian launcher from which missiles were fired at the Golan Heights was destroyed.

The Israel Air Force hit Syrian air defense batteries (SA-5 radar, SA-2, SA-22, SA-17) belonging to the Syrian army, that fired surface-to-air missiles on Israeli warplanes. The Britain-based Syrian Observatory for Human Rights estimated that at least 23 soldiers were killed in Israeli attacks, 5 Syrians and 18 "foreigners". The IDF estimated that nearly all Iranian infrastructure in Syria was hit.

After the incidents, Israeli Defence Minister Avigdor Lieberman said, "I hope we finished this chapter, and everyone got the message". Iranian Ayatollah Ahmad Khatami said, "The holy system of the Islamic Republic will step up its missile capabilities day by day so that... if [Israel] does anything foolish, we will raze Tel Aviv and Haifa to the ground." On May 22, Israel's air force commander, Major General Amikam Norkin, reported that Iran fired 32 rocket at Israel during the incidents, while more than 100 surface-to-air missiles were fired from Syria against Israeli jets. He also stated that IAF used its F-35 stealth fighters to attack Iranian targets, making Israel the first country in the world to carry out an operational attack with such aircraft.
