Israeli Prime Minister Benjamin Netanyahu faces mounting international and domestic pressure after the killing in Gaza of six captives, with U.S. President Joe Biden saying he is not doing enough to secure the release of hostages.

Britain said Monday it would suspend some arms exports to Israel, citing a "clear risk" they could be used in a serious breach of international humanitarian law.

UK Prime Minister Keir Starmer's government said that it's suspending exports of some weapons to Israel because they could be used to break international law — a move with limited military impact intended to increase pressure by Israel's frustrated allies for an end to the war in Gaza.

Foreign Secretary David Lammy said the U.K. government had concluded there is a "clear risk" some items could be used to "commit or facilitate a serious violation of international humanitarian law."

Israelis were plunged into grief and anger this weekend after the military said six hostages were killed by their captors in Gaza just as troops were closing in on their location. The rage sparked massive protests and a general strike — the most intense domestic pressure on Israeli Prime Minister Benjamin Netanyahu since the start of the war nearly 11 months ago.

Many Israelis blame Netanyahu for the mounting number of dead hostages and are calling for a cease-fire agreement to free the remaining roughly 100 captives — even if that means ending the conflict. Sunday's demonstrations were the largest show of support for a hostage deal since Oct. 7, when Hamas-led militants stormed into Israel and kidnapped 250 people.

Algeria has arrested seven people including four Moroccans accused of belonging to a "spy ring", prosecutors said on Sunday, less than a week before the country's presidential election.

Tunisia's electoral authority on Monday announced it had approved three presidential candidates for the October 6 election, dismissing three other would-be candidates despite court rulings allowing them to run.

A rare call for a general strike in Israel to protest the failure to return hostages held in Gaza led to closures and other disruptions around Israel on Monday, including at its main international airport. But it was ignored in some areas, reflecting deep political divisions.

Hundreds of thousands of Israelis poured into the streets late Sunday in grief and anger after six hostages were found dead in Gaza. The families and much of the public blamed Prime Minister Benjamin Netanyahu, saying they could have been returned alive in a deal with Hamas to end the nearly 11-month-old war.

President Joe Biden will sit down on Monday with U.S. negotiators pushing for a hostage-release deal in the Israel-Hamas war, the White House said, after the deaths of six captives in Gaza, including an American citizen.

Biden's official schedule was revised to make time for the White House meeting, which will also be attended by Vice President Kamala Harris, who is running to succeed him in November's presidential election.

Suspected attacks by Yemen's Houthi rebels targeted two ships in the Red Sea on Monday, authorities said, near where crews hope to salvage a tanker loaded with oil and still ablaze after another assault by the group.

The attacks are believed to be the latest in the Iranian-backed rebels' campaign that has disrupted the $1 trillion in goods that pass through the Red Sea each year over the Israel-Hamas war in the Gaza Strip as well as halted some aid shipments to conflict-ravaged Sudan and Yemen.

Israeli police said three people killed in Sunday's shooting attack in the occupied West Bank were members of the police force.

"Three members of the police force were killed this morning in a shooting attack," Ouzi Levy, chief of the Israeli police in the West Bank, told reporters at the scene of the attack near the Tarqumiya checkpoint near the city of Hebron.
