Israeli Prime Minister Benjamin Netanyahu's office on Tuesday denied American media reports that he will address the US Congress on June 13, amid mounting pressure to agree to a ceasefire with Hamas.

Netanyahu's office told Israeli media the date of his speech to Congress had "not been finalised", but it would not be on June 13 because it interferes with a Jewish holiday.

The date had been reported by Punchbowl News and Politico.

Iran's acting foreign minister Ali Bagheri said Monday his government was engaged in negotiations with arch-foe the United States hosted by the Gulf sultanate of Oman.

Asked about the issue at a news conference during a visit to Beirut, Bagheri said "we have always continued out negotiations... and they have never stopped."

Washington and Tehran have not had diplomatic relations since the 1979 Islamic Revolution in Iran.

Palestinian officials said Israeli forces shot dead two Palestinians in the occupied West Bank on Monday, as Israeli police confirmed undercover agents had killed a wanted man in the territory.

The Palestinian health ministry in Ramallah named the dead men as Adam Salahuddin Mansour Faraj, 23, and Mutaz Khaled Sadiq Nabulsi, 28.

Israeli police said undercover officers had killed "a senior wanted man" in the Balata refugee camp near Nablus.

Displaced Gazans had to use empty plastic bottles on Monday to try to remove sewage from their tents after a pipeline burst in the main southern city of Khan Yunis.

"All the tents were flooded with sewage water. This is no life," said Abdullah Barbakh, surrounded by bombed out buildings in the Palestinian city which has been devastated by months of war.

"I implore all Arab countries and the entire world to see what is happening to us. We're living in the middle of sewage."

On the same scorching day last month, Israeli troops fought street battles with Hamas militants in Gaza, its fighter jets struck Hezbollah targets in Lebanon and soldiers exchanged fire with Palestinian militants in the occupied West Bank.

As the war in the Gaza Strip nears its ninth month, Israel's military is getting pulled deeper into conflicts on multiple fronts and risks becoming overstretched, analysts told AFP.

Yemen's Iran-backed Houthis on Monday held a public funeral in the capital Sanaa for more than a dozen fighters they say were killed in US and British strikes last week.

The rebels had provided a death toll of 16 for the strikes overnight into Friday, which would make them among the deadliest since the United States and Britain launched a campaign in January to deter Huthi attacks on ships in the Red Sea and the Gulf of Aden.

The conservative speaker of Iran's parliament, Mohammad Bagher Ghalibaf, registered Monday his candidacy for the snap presidential election on June 28.

At the end of the five-day registration period on Monday evening, Interior Minister Ahmad Vahidi told reporters that a total of 80 applications have been submitted.

Israel on Monday announced the deaths of four captives held in Gaza amid growing doubts and international pressure over a plan for a ceasefire and hostage release deal outlined by US President Joe Biden.

Biden on Friday presented what he labelled an Israeli three-phase plan that would end the bloody conflict, free all hostages and lead to the reconstruction of the devastated Palestinian territory without Hamas in power.

Britain, France and Germany late on Monday submitted a resolution to the UN nuclear watchdog's board, censuring Iran over its lack of cooperation with the agency despite US opposition, two diplomats said.

It was the latest of numerous diplomatic manoeuvres by Western powers who fear Iran might be seeking to develop a nuclear weapon -- a claim the Islamic Republic has always denied.

"The text has been formally tabled," one diplomatic source told AFP, with a second confirming the information.

Ignored by Russia and Israel, the International Court of Justice is hamstrung by a dysfunctional global system that sees countries comply with its rulings -- or not -- based on their own double standards, experts say.

In 2022, the UN's highest court ordered Russia to halt its invasion of Ukraine, still underway two years later.

In May, it ordered Israel to immediately halt its military offensive in the southern Gaza city of Rafah, which is ongoing.
