Israeli Prime Minister Benjamin Netanyahu accused Iran on Monday of seeking the means to launch precision-guided missiles at Israel from Yemen, a signal that the war-torn Gulf Arab country could come under pre-emptive Israeli attack.

Netanyahu made his allegations, which were short on details, as he hosted a senior U.S. delegation and following days of unusually voluble warnings in Israel that war could break out with Iran or its allies on more than one front.

Neither Iran nor the Yemeni Houthi fighters it sponsors had an immediate response to Israel’s allegation. The Houthis use missiles and drones in their war against a coalition led by neighboring Saudi Arabia but there is scant public indication they possess weapons capable of traveling the some 2,000 km (1,240 miles) to Israel.

“Iran wants to develop precision-guided missiles that can hit any target in Israel within five to ten meters,” Netanyahu said in a speech in Jerusalem.

“Iran hopes to use Iran, Iraq, Syria, Lebanon and Yemen as bases to attack Israel with statistical missiles and precision-guided missiles. That is a great, great danger,” he said.

Earlier, addressing reporters ahead of meetings with U.S. Treasury Secretary Steven Mnuchin and top White House adviser Jared Kushner, Netanyahu reiterated Israeli suspicions, shared by Washington, that Iran has been trying to refit the rocket arsenal of Lebanon’s Hezbollah with precision-guidance systems.

“They seek also to develop that, and have already begun to put that in Yemen, with the goal of reaching Israel from there too,” said Netanyahu, who has urged the Trump administration to step up sanctions on the Iranians over their nuclear program and regional activities.

Aides would not elaborate on whether Netanyahu, in his remarks with Mnuchin at his side, meant to say that missile-conversion facilities were being installed in Yemen or that missiles capable of reaching Israel were already there.

An Israeli government source held out the prospect that Israel could take action. “This will cause Israel to be extremely vulnerable and this is something that we cannot just sit by and watch happening,” the source said.

With Israel in political deadlock after inconclusive elections in April and last month, Netanyahu has cited growing security concerns in urging his strongest rival, ex-general Benny Gantz, to form a broad coalition government.

“This is not a spin, this is not a line, this is a real thing that is happening as the power balance in the Middle East changes,” Netanyahu said. “We need a national unity government.”

Israel’s armed forces chief briefed Gantz about regional threats on Oct 16 and, last week, issued a public statement describing Israel’s northern and southern fronts as “tense and fragile and (liable to) deteriorate into conflict”.

When Israel refers to its northern front, it means Lebanon and more easterly Syria. “Southern front” usually refers to the Gaza Strip, in the southwest, where Hamas and Islamic Jihad militants receive Iranian funds. Yemen is to Israel’s southeast.

A senior Iranian military official, Abbas Nilforoushan, told the Tasnim news agency on Sept 28 that Iran had “surrounded it (Israel) from east, west, north and south”. 

Israel has signaled willingness to broaden its military campaign against suspected deployments by Iranian-fighters within striking distance of its borders. In addition to hundreds of Israeli bombing runs in Syria, Iranian-linked militias have accused Israel of carrying out attacks within Lebanon and Iraq.
