Lack of fuel from Israel brought Gaza's lone power plant to a halt on Friday, just 12 days after it was fired back to life following a seven-week shutdown, the Palestinian territory's electricity firm said.

"The plant stopped working on Friday morning due to a lack of fuel caused by Israel's closure of the Kerem Shalom crossing," an electricity company official said.

A rocket fired from the Hamas-ruled Gaza Strip in the early hours of Monday hit a southern Israel community without causing damage or injuries, Israeli police said.

Bomb disposal experts found the "rocket fired from the Gaza Strip" in a community near the city of Ashkelon, according to police spokesman Micky Rosenfeld. Police said the projectile hit near a school bus stop.

A Gaza-based human rights group on Sunday expressed "deep concern" at what it called Israeli troops' use of excessive force in Friday's fatal shooting of a young Palestinian.

The Palestinian Center for Human Rights said in a statement that soldiers shot dead Odah Jihad Hamad, 27, and wounded his brother Raddad, 22, as they picked through scrap in wasteland next to the Gaza-Israel frontier at Beit Hanun in the north of the coastal strip.

Israeli soldiers shot and wounded a Palestinian man in the southern Gaza Strip on Saturday, sources on both side of the border said.

Ashraf al-Qudra, a spokesman for the emergency services in the Islamist Hamas-run enclave, told AFP the 22-year-old was hit by a bullet east of Khan Yunis and moderately wounded.

Israel began transferring fuel to Gaza's sole power plant on Sunday, a Palestinian official said, as the Hamas-ruled enclave struggled to deal with massive flooding caused by winter downpours.

Raed Fatuh, a Palestinian Authority official in charge of the transfer of goods into Gaza, said Israel would be transferring 450,000 liters of fuel to the plant, which ground to a halt on November 1.

A Palestinian from the Gaza Strip was wounded by Israeli gunfire on Saturday evening after approaching the border fence, sources on both sides said.

A Hamas health ministry official told Agence France Presse, without elaborating, that the man was hit east of Khan Yunis in southern Gaza by Israeli tank fire.

An official said Saturday that Gaza's rescue service has evacuated more than 4,000 people from homes flooded after four days of heavy rain across the territory.

The downpour continued Saturday. It's part of a storm that covered Jerusalem and some of the West Bank with thick snow.

Israel is to allow construction materials for U.N. projects back into the Gaza Strip after reaching an agreement with the world body, officials said on Monday.

The ban on building materials was put in place on October 13 after troops discovered a sophisticated tunnel running under the Israel-Gaza border, built with the alleged aim of perpetrating anti-Israeli attacks.

A visit to Israel by Dutch Prime Minister Mark Rutte Sunday was marred by a dispute over a new security scanner on the Gaza border, an Israeli official said.

Rutte was to have inaugurated the scanner on the frontier with the Palestinian Islamist-ruled enclave, but the ceremony was put off because of the row.

The United Nations on Thursday began distributing fuel in Gaza to keep critical infrastructure running as fears of a health crisis grow over accumulating rubbish and sewage, an official said.

"Fuel is actually coming in, as of today, through the Kerem Shalom (goods crossing with Israel), purchased by UNRWA and distributed by the U.N.," U.N. Middle East special coordinator Robert Serry told a news conference in northern Gaza.
