JERUSALEM (Reuters) - Israel announced on Friday it was sharply reducing its military operations in the West Bank and Gaza Strip in response to efforts by Palestinian President Mahmoud Abbas to end attacks on Israelis.

The new rules of engagement, issued soon after Palestinian paramilitary police widened their control in the Gaza Strip, put limits on the assassinations of militants and followed a call by Abbas for Israel to agree to a cease-fire with gunmen.

But in a sign of challenges for Abbas and his hopes of reviving peacemaking, final results in Gaza council elections showed the Islamic militant group Hamas swept nearly two-thirds of the seats, winning control of 7 out of 10 councils.

"The clear message to the Zionist entity is that the program of the resistance led by Hamas ... can carry out achievements in other areas," senior group leader Mohammed al-Zahar told reporters in Gaza.

Backing away from confrontation after more than four years of violence, the Israeli military said in a communique: "Proactive army operations in the Gaza Strip will cease in the areas in which Palestinian security forces have redeployed."

It said "army targeting of terrorists in the West Bank will take place only if there is an immediate threat by active terrorist cells" and only with explicit authorization from the chief of staff, Moshe Yaalon.

The statement said Yaalon had decided on the moves "in light of the ongoing cooperation" between Israeli and Palestinian officials. Arrangements would also be made to reopen next week Gaza border crossings closed after attacks by gunmen.

Responding to the Israeli announcement, Palestinian cabinet minister Saeb Erekat called on Israel to declare a full cessation of violence against Palestinians.

"We have a similar obligation to stop violence against Israelis anywhere in line with the ´road map´," he said about a U.S.-backed peace plan charting mutual steps toward creation of a Palestinian state alongside a secure Israel.

GOODWILL

At the World Economic Forum in Davos, Switzerland, Israeli Vice Prime Minister Ehud Olmert and Palestinian officials hailed a new mood of goodwill since Abbas´s election on Jan. 9 on a platform of non- violence to replace the late Yasser Arafat.

"A window of opportunity, a dramatic change is shaping up and taking place," said Olmert, a close ally of Prime Minister Ariel Sharon.

Building on a northern Gaza deployment a week ago, 2,000 Palestinian paramilitary police fanned out across the southern part of the occupied territory, which they have not patrolled since 2001.

The United States and Israel have said the Palestinians must crack down on militant attacks on Israelis before peacemaking can move forward.

Over the past week, violence has dropped sharply in the Gaza Strip, where Abbas is trying to coax militants into a truce they demand Israel also accept in the run-up to a planned Israeli withdrawal this summer.

Zahar said Hamas would still not accept a truce unless Israel agreed to conditions it still has not promised to fulfill, including freeing Palestinian prisoners.

With Palestinian flags flying from their vehicles, paramilitary police drove in a convoy to Gaza´s border with Egypt, where Israel has mounted punishing raids in residential areas to root out weapons- smuggling tunnels and gunmen.

Other contingents armed with assault rifles took up positions between Jewish settlements on occupied land, frequently hit by mortar bombs and rockets fired by militants, and Palestinian towns.

"I am very happy. Now we can sleep in peace," said Salah al-Najar, who lives near the Jewish settlement of Morag. "My children were constantly afraid of noises Israeli tanks made."

In a sign of a new push for peace, U.S. officials said Secretary of State Condoleezza Rice would visit the region early next month. Palestinian officials said she would hold talks in Israel and the West Bank on Feb. 6 and 7.
