The Netherlands can continue to deliver parts for F-35 fighter jets used by Israel in the Gaza Strip, after a Dutch court on Friday threw out a case brought by a group of human rights organisations.

The district court in The Hague said that supplying the parts was primarily a political decision that judges should not interfere with.

"The considerations that the minister makes are to a large extent of a political and policy nature and judges should leave the minister a large amount of freedom," the court ruled.

Fighting between the Sudanese army and paramilitaries on the outskirts of Wad Madani sent already displaced families fleeing again Friday, an AFP correspondent reported, as a civil war entered its ninth month.

The army blocked civilians from entering the city of Wad Madani -- 180 kilometres (110 miles) south of the capital Khartoum -- which had quickly become a safe haven when war broke out between the Sudanese armed forces and the paramilitary Rapid Support Forces on April 15.

France's foreign minister travels to Lebanon on Saturday as part of diplomatic efforts by President Emmanuel Macron's government to help contain the Middle East conflict.

Fears of a widening war have been growing, with Iran-backed groups targeting US and allied forces in Iraq and Syria, and daily exchanges of fire along Israel's border with Lebanon.

"We must avoid a regional eruption," foreign ministry spokesman Christophe Lemoine said ahead of Foreign Minister Catherine Colonna's trip.

A court in the Netherlands will rule Friday on whether to force the Dutch government to stop supplying parts for F-35 fighter jets being used by Israel over the Gaza Strip.

A group of human rights organisations has brought the case, arguing that supplying the parts contributes to alleged violations of international law by Israel in its war with Hamas.

The case concerns US-owned F-35 parts stored at a warehouse in the Netherlands and then shipped to several partners, including Israel, via existing export agreements.

Israel reopened an aid crossing into Gaza on Friday as staunch ally the United States urged more restraint in its all-out offensive against Hamas.

The Israeli army said its troops had shot and killed three hostages after mistaking them for a "threat" while Jerusalem came under rocket fire from Gaza for the first time since late October.

The war began after Hamas launched an unprecedented attack on Israel on October 7 that Israeli officials say killed around 1,200 people, mostly civilians.

Hours after the applause and relief that the world had finally reached a landmark climate agreement in Dubai, US special envoy John Kerry admitted that he thought it might never happen.

The seasoned international negotiator recalled a conversation with one minister who worried about a deal that would signal the end of fossil fuels.

"One minister from one of those countries involved said, 'John, you can't ask us to commit economic suicide'," Kerry said.

The United States told Israel on Wednesday to scale down its war on Hamas in the "near future," with President Joe Biden urging it to take more care to save civilian lives in Gaza.

US National Security Advisor Jake Sullivan made the push during talks in Tel Aviv with Prime Minister Benjamin Netanyahu and other senior officials, discussing the war Israel launched after the October 7 attacks.

Washington has strongly backed Israel's right to defend itself, but mounting civilian casualties in the Palestinian territory have caused a growing rift between the close allies.

Spanish Foreign Minister Jose Manuel Albares said Thursday that Israel should distinguish between "terrorist targets" and civilians in Gaza, adding that places of worship, hospitals and UN buildings should be spared.

"Spain's voice will always be raised to protect the rights of the Palestinian civilian population in Gaza," Albares said on a visit to Morocco.

Kibbutz Nahal Oz was supposed to celebrate the 70th anniversary of its founding near Gaza on October 7 -- the day Hamas militants launched their deadly attack on southern Israel.

More than two months on, its deeply traumatised residents are settling in for a year of displacement on the opposite side of the country.

With fighting between Israel and Hamas showing no sign of abating, kibbutzniks from 20 evacuated communities are making longer-term relocation plans from their homes near the Gaza Strip.

Israeli forces killed 11 people in a multi-day raid in the occupied West Bank, the Palestinian health ministry said Thursday.

The latest death was a 17-year-old boy who the ministry said was shot in the chest by the Israeli army in Jenin.

In addition to 11 killed by Israeli forces, Palestinian health officials said a sick 13-year-old boy also died after Israeli forces prevented him from reaching hospital.

Israeli troops launched their incursion into the northern city of Jenin and its refugee camp early Tuesday and were still present on Thursday afternoon.
