The Shin Bet security service has announced the arrest of a number of Israeli Arabs suspected of contacting Hizbullah in an alleged attempt by the party to carry out attacks in the Jewish State, Israeli media reported.

Four men were arrested in Israel for having direct contact with Hizbullah, the Shin Bet said in a statement on Thursday.

Israel is to ease restrictions on its two crossings into Gaza to allow greater movement of people and goods under terms of a ceasefire agreement that ended the 50-day conflict.

Erez which lies at Gaza's northern edge is a personnel crossing, while Kerem Shalom, which lies at the southernmost point of the Gaza-Israel border, is the only transit point for aid and goods coming from Israel.

Vital humanitarian aid poured into Gaza on Thursday as residents began rebuilding their lives following a devastating 50-day war between Israel and Hamas that experts say left no winners.

Millions in and around the war-torn coastal enclave were enjoying a second day of peace after the guns fell silent following a permanent ceasefire agreement that conditioned the easing of Israel-imposed goods and movement restrictions on the territory.

"She will call me Daddy and Mummy," insisted 11-year-old Amir Hamad, cradling his infant sister in his arms after the Gaza war left him and his four siblings orphans.

Fifty days of bloody fighting in and around the wartorn Gaza Strip has cost the lives of nearly 500 children, but it has also turned hundreds more into orphans, who face a future deprived of their parents' love.

A new poll has shown that a majority of Israelis are skeptical of Prime Minister Benjamin Netanyahu's claim that Israel achieved a "great military and political" victory over Hamas in the latest round of fighting in the Gaza Strip.

The poll, published in Thursday's Haaretz newspaper, shows that 54 percent of those surveyed believe there was no clear winner the 50 days of war. The fighting killed more than 2,100 Palestinians and 69 Israelis.

Israeli Prime Minister Benjamin Netanyahu said on Wednesday that Islamist foe Hamas had achieved none of its demands in a truce ending 50 days of deadly conflict in Gaza.

"Hamas was hit hard and got none of its demands," Netanyahu said at a news conference in Jerusalem, his first comments since the ceasefire went into effect on Tuesday evening.

Israel and Palestinians both boasted of victory in the Gaza war but analysts say Hamas received only promises while the conflict aggravated divisions in the Israeli leadership.

"After 50 days of fighting, both sides were exhausted so that's why they reached a ceasefire," said Middle East analyst Eyal Zisser of the Israeli Moshe Dayan Institute.

A truce deal between Israel and Hamas may have ended 50 days of bloodshed in Gaza but it also exposed a clear split within Prime Minister Benjamin Netanyahu's ruling coalition.

The ceasefire, effective from 1600 GMT on Tuesday, was accepted by Netanyahu following consultations with his Defense Minister Moshe Yaalon, press reports said.

Shopkeepers reopened and fishermen put out to sea on Wednesday as Gaza's 1.8 million people breathed a collective sigh of relief after a truce ended 50 days of bloodshed.

For the most part, there was a sense of hope on the streets after the surprise ceasefire came into force at 1600 GMT on Tuesday, ending seven weeks of violence which killed more than 2,140 in Gaza and 70 on the Israeli side.

Israel closed off the area around Quneitra on the occupied Golan Heights on Wednesday after an officer was wounded by stray fire as Syrian rebels seized control of the crossing.

The U.N. peacekeeping force which monitors the armistice line said several mortar rounds struck near its positions as rebel fighters, including some from al-Qaida affiliate Al-Nusra Front, stormed the crossing in deadly fighting with government troops.
