An Israeli Arab rights group on Thursday called for an international investigation into alleged Israeli war crimes during the latest Gaza conflict, a week after the army dismissed several cases.

The army announced on September 10 it launched five criminal investigations into incidents involving its forces during the 50-day conflict that killed more than 2,140 Palestinians and 73 people on the Israeli side.

The Israeli army on Thursday continued fortifying its posts opposite the southern Lebanese town of Adaisseh in order to conceal the movements of its troops and vehicles, Lebanon's National News Agency reported.

It “cemented and fortified the military posts along the border with Lebanon facing the Adaisseh-Kfarkila road,” NNA said.

Israeli naval gunfire wounded a fisherman off the coast of Gaza on Thursday, a medical official said, in a sign of ongoing tension around the battered Palestinian territory.

The man was moderately wounded in the incident, emergency services spokesman Ashraf al-Qudra told Agence France Presse, without providing further details.

The Middle East Quartet of peacemakers on Wednesday joined calls for a quick start to the rebuilding of war-ravaged Gaza before the current truce with Israel ends in renewed violence.

"The precarious situation in Gaza and southern Israel, the danger that violence could flare up again at any point, are precisely the reason to move as quickly as possible on the short-term and long-term recovery efforts," Quartet envoy Tony Blair wrote in remarks published by his office ahead of a meeting on international aid to the Palestinians.

Israel's Intelligence Minister Yuval Steinitz on Wednesday urged the European Union not to make a "bad deal" with Iran over its nuclear program, ahead of crucial talks.

Palestinians fired a mortar round into southern Israel Tuesday in the first attack since an August 26 ceasefire, without causing any casualties, the Israeli army said.

"For the first time since operation Protective Edge, a mortar shell fired from Gaza hit southern Israel," Lieutenant Colonel Peter Lerner said on Twitter, referring to the military offensive in Gaza.

Israeli settlers in the occupied West Bank numbered 382,031 at the end of June, up from 374,469 six months earlier, the leading settler organization said on Tuesday.

The number does not include annexed east Jerusalem, which Israel has declared to be an integral part of the Jewish state and an inseparable component of its capital. Around 200,000 Israelis live in the eastern Arab sector of the city.

The United Nations has brokered an Israeli-Palestinian deal on imports of construction materials to Gaza to ensure they will not be diverted by Hamas militants, an envoy said Tuesday.

The agreement on monitoring the supply of materials "must get up and running without delay," said Robert Serry, the U.N. envoy for the Middle East.

Israeli police said Tuesday they arrested 22 Palestinians in annexed Arab east Jerusalem overnight on suspicion of throwing stones and petrol bombs, as three months of protests showed no let-up.

It brought to 700 the number of arrests in east Jerusalem since July, police spokeswoman Luba Samri said in a statement, including 50 this month alone.

A proposed sale of Israeli weapons including drones to Ukraine has been blocked for fear of antagonizing Russia, Channel Two television reported on Monday.

The broadcaster said a Ukrainian delegation had visited Israel with a view to acquiring military hardware including drones to use against pro-Russian separatists.
