Israeli Prime Minister Benjamin Netanyahu warned Tehran on Saturday over aggressions by what he called Iran and its "proxies" in Syria, while showing what he claimed was a piece of an Iranian drone shot down in Israeli airspace.
Saying he had "a message to the tyrants of Tehran" during a speech at the Munich Security Conference, he warned: "Do not test Israel's resolve."
He brandished a rectangular piece of dark green metal which he called "a piece of that Iranian drone, or what's left of it after we shot it down."
Israel has said it shot down the drone on February 10 after it entered the country from Syria, and responded with a raid on what it said was the Iranian control systems for the craft in Syria.
During the strikes, one of Israel's F-16 fighter jets was shot down, believed to be the first loss of an Israeli plane in combat since 1982.
Israel's response marked the first time it publicly acknowledged hitting Iranian targets in Syria since the 2011 start of the civil war there.
Netanyahu later tweeted, “Mr. Zarif: do you recognize this? You should. It’s yours. Don’t test Israel’s resolve,” alongside a video-cut of his remarks at the security conference.
The Israeli military has claimed the drone was a copy of a US model captured by Iran in 2011, based on an analysis of the drone's debris.
Tensions between the two countries have been building in recent months, with Israel fearing that Tehran is trying to establish a permanent presence in Syria as part of an effort to become a greater regional power in the Middle East.
But Netanyahu said Sunday that Israel would not let Iran obtain a permanent foothold in its northern neighbour.
"Through its proxies -- Shiite militias in Iraq, the Huthis in Yemen, Hezbollah in Lebanon, Hamas in Gaza -- Iran is devouring huge swathes of the Middle East," he said.
"Israel will not allow Iran's regime to put a noose of terror around our neck," he added.
"We will act without hesitation to defend ourselves. And we will act if necessary not just against Iran's proxies that are attacking us, but against Iran itself."
But he stressed that Israel was not the enemy of the Iranian people, and offered his condolences to the families of the 66 people killed in an Iranian plane crash Sunday.
"We have no quarrel with the people of Iran, only with the regime that torments them," Netanyahu said.
