Israel says it has inflicted huge damage on Syrian air defenses after one of its fighter jets was brought down during a raid over Syria.
The response was the “most significant attack” of its kind against Syria since the 1982 Lebanon war, said senior Israeli air force general Tomer Bar.
The F-16 jet went down during a mission that followed an Iranian drone launch into Israeli territory, Israel says.
The two pilots parachuted to safety before the crash in northern Israel.
Israel says it responded with a second wave of strikes on both Syrian and Iranian military targets operating inside Syria.
Israeli air strikes in Syria are not unusual, BBC Middle East correspondent Tom Bateman says, but the loss of an Israeli fighter jet marks a serious escalation.
Later on Saturday, Israeli Prime Minister Benjamin Netanyahu held a meeting with his military chiefs. He said Israel wanted peace but would defend itself “against any attack against us or any attempt by Iran to establish itself against us in Syria”.
In other developments:
- A Turkish helicopter was shot down as the country continued its offensive against Kurdish fighters in northern Syria. Two soldiers on board were killed, the Turkish military says
- UN Human Rights Commissioner Zeid Ra’ad al-Hussein said the past week was one of the bloodiest in Syria since the conflict began in 2011 – with at least 277 civilian deaths reported
Israeli aircraft then attacked Syrian and “Iranian targets in Syria”, the military says.
Syria’s state media say air defences opened fire in response to an Israeli attack on a military base, hitting more than one plane.
The damaged F-16 came down in an empty field near the town of Harduf in northern Israel.
It is unclear how exactly the plane was brought down. Gen Bar said it faced massive anti-aircraft fire, forcing the two pilots to eject.
He said the crew did not report being hit before abandoning the aircraft.
They were taken to hospital, one of them “severely injured”, the Israeli military said.
What did Israel do next?
Israel launched a second wave of strikes in Syria. Eight of the Syrian targets belonged to the fourth Syrian division near Damascus, IDF spokesman Jonathan Conricus said.
All the Israeli aircraft from this sortie returned safely.
“We are not looking to escalate the situation,” he added.
Syria and its ally Iran deny that the drone entered Israel. Russia expressed “serious concern” over the Israeli air strikes and called for all sides to show restraint.
What is the Iranian presence in Syria?
Iran is Israel’s arch-enemy, and Iranian troops have been fighting rebel groups since 2011.
Tehran has sent military advisers, volunteer militias and, reportedly, hundreds of fighters from its Quds Force, the overseas arm of the Iranian Revolutionary Guards Corps (IRGC).
It is also believed to have supplied thousands of tonnes of weaponry and munitions to help President Bashar al-Assad’s forces and the pro-Iranian Hezbollah, which is fighting on Syria’s side.
Tehran has faced accusations that it is seeking to establish not just an arc of influence but a logistical land supply line from Iran through to Hezbollah in Lebanon.
A powerful new element
Analysis by BBC’s diplomatic correspondent Jonathan Marcus
For years Israel has been striking at weapons stores and other facilities in Syria with a single goal – to disrupt and, as far as possible, to prevent advanced Iranian missiles being delivered to Hezbollah in Lebanon.
Syria has often been the conduit for these shipments, but the changing balance of power there, with the survival of the regime of President Bashar al-Assad bolstered by Iranian help, has introduced a powerful new element – a direct Iranian role in the crisis.
