JERUSALEM - A majority of Israelis support a new truce with the militants of Hamas but doubt it will last for long, a new poll showed Friday.

The poll in the daily Yediot Ahronoth showed that 56 percent of Israelis support the one-day-old truce, which was mediated by Egypt. But 79 percent said they do not believe or are inclined not to believe that it will last for long.

The poll was conducted by the Dahaf Institute and included 500 respondents. It had a margin of error of 4.4 percentage points.

The Egyptian-mediated cease-fire in Gaza went into effect Thursday morning, ending Palestinian rocket attacks on Israeli towns from the coastal strip and bringing a halt to Israeli military raids and airstrikes there.

In the West Bank, which is not covered by the truce, paramedics said two Israelis were shot by Palestinians as they hiked near the settlement of Neve Tsuf, 12 miles (20 kilometers) northwest of Jerusalem. No further details were immediately available.

Next week, Israel is supposed to begin easing its blockade of Gaza, imposed when Hamas violently siezed power a year ago and tightened because of ongoing attacks.

Seventy-eight percent of those questioned told pollsters that the agreement should have been made contingent on the release of Gilad Schalit, an Israeli soldier held by Hamas for two years. Israeli leaders said there would be no cease-fire without Schalit's release, but in the end the sides agreed only to continue negotiations on a prisoner swap that would see him freed in return for Palestinian prisoners.

Also Friday, Israeli security officials said Friday that students from a far-right Jewish theological seminary at a West Bank settlement recently built a crude rocket and fired it a nearby Palestinian village. It failed to reach its target and caused no injuries.

The officials spoke on condition of anonymity because the incident, which occurred about two weeks ago, is still under investigation.

Police spokesman Danny Poleg said detectives searched the settlement Thursday and questioned residents but made no arrests and found no explosives. He would not comment further.

Yitzhar is a known hotbed of ultranationalist Israelis who believe that the West Bank is part of the biblical land of Israel promised to the Jewish people by God and oppose any concessions to the Palestinians.
