Israel moved closer to early elections Friday after Prime Minister Benjamin Netanyahu's main coalition partner, the ultra-nationalist Jewish Home party, said it wants a vote "as soon as possible," and will press for consultations on a date on Sunday.

The call for early elections came after a meeting Friday between Netanyahu and Education Minister and Jewish Home leader Naftali Bennett. The two men have been locked in a tense rivalry, with Bennett often criticizing Netanyahu from the right.

Bennett had demanded the post of defense minister, after the incumbent, Avigdor Lieberman, resigned earlier this week in protest over Netanyahu's Gaza policies.

A senior Jewish Home official said it became clear after the Bennett-Netanyahu meeting that there "is a need to go to elections as soon as possible." He spoke on condition of anonymity because he was discussing the content of a closed meeting.

The official said leaders of coalition parties will meet Sunday to coordinate the date for early elections.

The apparent failure of the Netanyahu-Bennett meeting seemed to seal the coalition's fate.

The departure of Lieberman and his Israel Beitenu party had left the coalition with a one-seat majority in the 120-member parliament. Without Bennett's Jewish Home, Netanyahu's coalition would lose its parliamentary majority.

The political crisis began with a botched Israeli undercover raid in Gaza on Sunday. The raid led to two days of intense cross-border fighting. Gaza's Hamas rulers fired hundreds of rockets at southern Israel, while Israeli warplanes targeted scores of targets in Gaza.

After two days, Egypt brokered an informal truce between Israel and the Islamic militant Hamas. Netanyahu averted a war, but drew blistering criticism from ultra-nationalists.

Lieberman resigned in protest on Wednesday.

On Friday, he toured southern Israel and accused Netanyahu of being soft on terrorism. He said Netanyahu's Gaza policy is strengthening Hamas.

Lieberman alleged that the truce will put southern Israel under a growing threat from Hamas, similar to the threat posed to northern Israel by Lebanon's heavily armed Hezbollah militia.

"It's impossible that after Hamas launches 500 rockets at the Israeli border communities. the heads of Hamas are actually getting immunity from the Israeli cabinet," he told reporters.

"We are now feeding a monster" that will only grow if not stopped, he said. "Within a year we will have a twin brother of Hezbollah, with all the implications."
