Israeli troops opened fire on more than 100 Palestinian protesters in the northern West Bank on Friday, an AFP correspondent said, wounding at least one person.

Soldiers fired live rounds at Palestinian youths who hurled stones at them at the entrance to the Jalazun refugee camp north of the city of Ramallah, the correspondent said.

Final opinion polls on Friday put Israeli Prime Minister Benjamin Netanyahu's right-wing Likud party four seats behind its center-left rival with four days to go before a general election.

Several polls released Friday -- the last day opinion surveys can be released before Tuesday's vote -- showed the Zionist Union pulling further ahead of Likud after an intense campaign.

Final opinion polls published Friday put Israeli Prime Minister Benjamin Netanyahu's Likud party four seats behind its centre-left rivals, days before the general election.

The top-selling Yediot Aharonot showed Likud's main challenger, the Zionist Union coalition, winning 26 of the 120 seats in parliament against 22 for Netanyahu's party.

Former Israeli president Shimon Peres on Thursday endorsed Labor head Isaac Herzog for prime minister, five days before a snap general election.

"I support Issac Herzog for prime minister," said Peres, himself a long-time Labor member and leader.

Progressive Socialist Party leader MP Walid Jumblat on Thursday urged the Druze Arabs in Israel to run in the upcoming legislative polls in “unified” lists with the aim of achieving “drastic change.”

“Once again I address this appeal to the Druze Arabs in occupied Palestine, who are suffering along with their Palestinian brothers from occupation, tyranny and injustice due to the practices of Israel, which is seeking to totally eradicate the Arab identity,” said Jumblat in a statement.

Hizbullah hailed on Thursday the Egyptian government's appeal against a ruling that considered the Palestinian group Hamas as a terrorist organization.

The party's media office deemed the step as “positive,” calling for dialogue between it and Hamas to “improve their ties.”

Israelis vote next week in an election seen as a referendum on the tenure of Prime Minister Benjamin Netanyahu, who could lose but still secure a new term in power.

Netanyahu, 65, called for the March 17 vote late last year as his coalition government teetered on the brink of collapse. It will be Israel's third election since 2009 and the premier's biggest challenge after six years at the helm.

Less than a week before Israel's second general election in two years, Isaac Herzog's center-left Zionist Union opened up a lead on Prime Minister Benjamin Netanyahu's right-wing Likud, polls showed Wednesday.

The March 17 vote comes as Israel faces major domestic and international challenges, all of which will have to be addressed by the next government - among them the Iranian nuclear threat, the deadlock in peace efforts and a looming Palestinian legal move at the International Criminal Court.

An Israeli army officer was wounded Tuesday by gunfire from the Syrian side of the Golan Heights, the military said, in what was believed to have been a deliberate attack.

"During a routine IDF (Israel defense force) activity in the Golan Heights, shots were fired at an IDF force," a statement read.

Israeli authorities on Tuesday demolished an EU-funded shelter in Arab east Jerusalem, the European Union said, denouncing the move.

"We condemn today's demolition of temporary shelters funded by the European Union... as part of its response to the needs of the affected communities," an EU statement said.
