JERUSALEM/BEIRUT (Reuters) - Anti-aircraft fire downed an Israeli warplane returning from a bombing raid on Iran-backed positions in Syria on Saturday in the most serious confrontations yet between Israel and Iranian-backed forces based across the border.
The F-16, one of at least eight Israeli planes despatched in response to what Israel said was an Iranian drone's incursion into its airspace earlier in the day, was hit by a Syrian anti-aircraft missile and crashed in northern Israel, an Israeli official told Reuters.
Both pilots ejected and were injured, one critically.
Israel then launched a second and more intensive air raid, hitting what it said were 12 Iranian and Syrian targets in Syria, including Syrian air defence systems.
Lebanon's Iran-backed Hezbollah group said the downing of the plane marked the "start of a new strategic phase" that would limit Israel's ability to enter Syrian airspace.
Iran's involvement in Syria in support of President Bashar al-Assad in a nearly 7-year-old civil war - including the deployment of Iran-backed forces near the Israeli-occupied Golan Heights - has alarmed Israel, which has said it would counter any threat.
But Israel and Syria signalled they were not seeking wider conflict, even as Prime Minister Benjamin Netanyahu rushed to military headquarters in Tel Aviv and the pro-Assad alliance pledged a strong response to any Israeli "terrorist action".
"Israel seeks peace but we will continue to defend ourselves steadfastly against any attack against us or any attempt by Iran to establish itself against us in Syria," Netanyahu said in a televised statement.
Russia, whose forces began intervening on behalf of Assad in 2015, expressed its concern and urged both sides to exercise restraint and avoid escalation.
Netanyahu said he had spoken by telephone with Russian President Vladimir Putin and that they agreed Israel-Russia military coordination in regard to Syria would continue.
Putin told Netanyahu in the phone call that there was a need to avoid any steps that would lead to a new confrontation in the region, Interfax news agency reported.
A Western diplomat in the region said: "My impression is that it seems to be contained at this point. I don't think anybody wants to escalate further."
A Pentagon spokesman said the United States fully supported Israel's right to defend itself, and a State Department spokeswoman said the United States is "deeply concerned" about the "escalation of violence over Israel's border."
U.N. Secretary-General Antonio Guterres is closely watching the "alarming" military escalation throughout Syria and calls on all sides to exercise restraint and work for an immediate and unconditional de-escalation of violence, a U.N. spokesman said.
CHAIN OF EVENTS
Saturday's chain of events began at 4:30 a.m. (0230 GMT) when an Israeli Apache helicopter shot down an Iranian drone over the northern town of Beit Shean, the Israeli military said.
The drone had been sighted taking off from a base in Syria, and was intercepted after it crossed into Israeli territory, spokesman Lieutenant Colonel Jonathan Conricus said.
Israeli planes then struck an Iranian installation in Syria from which, the Israeli military said, the unmanned aircraft had been operated.
The Israeli military released grainy black and white footage of what it said was the drone's control vehicle in Syria being destroyed.
The F-16 crashed on its return from the mission, coming down in an empty field near Harduf, east of Haifa.
"We heard a big explosion and then sirens. We didn't know what was happening, we heard helicopters and planes," said Yosi Sherer, 51, who was staying at a hostel in Beit Shean.
Flights at Tel Aviv's international airport were briefly halted.
The area was quiet by mid-afternoon.
Conricus said missile remnants were found near the crash site. "We don't know yet if it's an SA-5 or SA-17, but it's a Syrian anti-aircraft missile," he said.
Israel then launched a second bombing raid in Syria.
The pro-Assad military alliance said Israel had attacked a drone base in central Syria but denied any of its drones had entered Israeli airspace. Iran rejected the Israeli version of events as "ridiculous".
David Ivry, a former Israeli Air Force chief, told Reuters he believed it was the first time an Israeli F-16 was brought down since Israel began using the jets in the 1980s.
Israel has long maintained air superiority in the region, mounting air strikes in Syria on a regular basis, targeting suspected weapons shipments to Hezbollah.
Hezbollah said in a statement: "Today's developments mean the old equations have categorically ended."
Iranian and Iran-backed Shi'ite forces, including Hezbollah, have deployed widely in Syria in support of Assad. Iran's military chief warned Israel last October against breaching Syrian airspace and territory.
Netanyahu, visiting the Golan on Tuesday, peered across the border into Syria and in public remarks warned Israel's enemies not to test its resolve.
An official in the pro-Assad alliance said after the downing of the F-16 that a "message" had been sent to Israel. But he added: "I do not believe matters will develop to a regional war."
The Israeli military said it did not seek escalation, calling its action a defensive response to an Iranian act of aggression.
The U.S. administration has backed Israel's hawkish stance on Iran and declared containing Tehran's influence an objective of its Syria policy. On a visit to Israel last month, U.S. Vice President Mike Pence called Iran the world's "leading state sponsor of terror".
Pentagon spokesman Adrian Rankine-Galloway said the United States fully supports Israel's right to defend itself.
"We share the concerns of many throughout the region that Iran's destabilising activities ... threaten international peace and security, and we seek greater international resolve in countering Iran's malign activities," Rankine-Galloway said.
U.S. Secretary of State Rex Tillerson is expected to visit the region in the coming week to discuss Syria and other issues, and is scheduled to visit Jordan, Turkey, Lebanon and other countries. Netanyahu said he and Tillerson discussed the flare-up on Saturday.
Tensions also have spiked across the frontier between Israel and Lebanon over Israeli plans for a border wall, and Lebanese plans to exploit an offshore energy block partly located in disputed waters.
Israel captured the Golan Heights from Syria in the 1967 war and has occupied it since, annexing the territory in 1981 in a move not recognised internationally.
There has been an uneasy standoff since a ceasefire that followed a war in 1973, with United Nations observer forces manning a buffer zone between the two armies.
In November, Israel said it had shot down a Syrian reconnaissance drone over the demilitarized zone, and on Feb. 8 shots were fired from Syrian territory at an Israeli drone, hitting a house in Majdal Shams, in Israeli-occupied Golan.
