February 2018 Israel–Syria incident

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 spying on Israel. Two hours after the downing of the jet, Israel began attacking additional targets inside Syria, including air defense sites and Iranian targets near Damascus. Israel stated it destroyed the Syrian military’s main command and control bunker. Iran dismissed the Israeli allegation of Iranian drone incursion into Israeli territory as "ridiculous" and a pro-Syrian military alliance said that Israel actually hit a drone base which was used in the fight against ISIS.

It was the first time Israel and Iran confronted each other directly since the Iranian Revolution of 1979 and the beginning of the Iran–Israel proxy conflict. Israel stated that it was "the biggest and most significant attack the air force has conducted against Syrian air defenses since the 1982 Lebanon War". Hezbollah said that the downing of the F-16 was the beginning of "a new strategic phase", as it was the first occasion on which Israel lost a jet to an enemy combatant since 1982.

Timeline
At 4:30am on 10 February 2018, an Israeli AH-64 Apache helicopter shot down an Iranian-produced copy of the RQ-170 drone (Saegheh) near the northern town of Beit Shean. The Iranian drone was sighted taking off from a base in Syria, flew along the Jordanian border, and was intercepted 90 seconds after crossing the Israeli border. Israeli journalist Ron Ben-Yishai said that the Iranian drone was sent to test if the Israeli air defense systems could detect a stealth drone – a test which had failed.

In response to the sighting of the drone crossing the Israeli border, 8 F-16s of the Israeli Air Force (IAF) struck Tiyas Military Airbase from which the Israeli military said the drone had launched, very likely with standoff weapons. This base was attacked by the IAF in the past (March 2017), despite warnings from Russia due to its proximity to Russian military personnel. The attack prompted a response from Syrian Air Defense systems, which after firing on the Israeli jets, shot down an Israeli F-16I fighter jet over northern Israel. Two weeks later, Israeli Defence Forces (IDF) stated that the F-16I was hit by a S-200 surface-to-air missile (SAM) with the crew failing to take proper evasive actions. The same statement reported that 13 SAMs had been fired at the 8 F-16Is which took part in the initial attack, with another 14 SAMs fired during the subsequent attack flights, resulting in a total of 27 missiles fired on the attacking jets.

The F-16I was flying at high altitude to verify the results of the strike on Syrian targets, which made it easy to track by Syrian air defenses.

Aftermath
Sirens were heard in the early morning in northern Israel and flights at Tel Aviv's international airport were briefly halted. Israeli Prime Minister Benjamin Netanyahu held security consultations following the incident, and Israel conducted several attacks against the Syrian Aerial Defense System and targets which Israel says are Iranian targets in Syria in response to the downing of the F-16. The Wall Street Journal cited Syrian media reporting that 25 people were killed by the Israel airstrikes.

Prime Minister of Israel Benjamin Netanyahu said "They dispatched an Iranian drone from Syrian territory into Israel. ... Israel holds Iran and its Syrian hosts responsible."

The Syrian Assistant Foreign Minister, Ayman Sussan said that they "have full confidence the aggressor will be greatly surprised, because it thought this war—this war of attrition Syria has been exposed to for years—had made it incapable of confronting attacks." He said Israel will meet new surprises should they attack Syrian again.

In Syria the events were viewed as a game-changer given that it was the first time the Syrian government made good on promises to respond to violation of its territory. The government supporters celebrated the downing of the Israeli jet and hailed the Syrian army and President Bashar Assad.

At the Munich Security Conference, Netanyahu showed an object that he said was part of the downed drone.

Strategic significance
This incident is extremely unusual, as it is the first time Israel and Iran confronted each other directly since the Iranian Revolution of 1979 and the beginning of the Iran–Israel proxy conflict. Israel stated that it was "the biggest and most significant attack the air force has conducted against Syrian air defenses since the 1982 Lebanon War". Hezbollah said that the downing of the F-16 is the beginning of "a new strategic phase", as it was the first occasion on which Israel lost a jet to an enemy combatant, since 1982.

Hezbollah suggested that the incident put an end to Israel's long-standing air superiority.

An Israeli army assessment stated that the twelve retaliatory air strikes destroyed nearly half of Syria's aerial defense systems, which include over 900 launchers. However, a day earlier, the Israeli military put the number of destroyed aerial defense batteries at three.

On 14 February, Haaretz reported that the Israeli strikes only ended after an afternoon phone call between Vladimir Putin and Benjamin Netanyahu.
