ADEN, June 8 (Reuters) - Yemen's Iran-aligned Houthis said on Monday that they would ban Israeli maritime navigation in the Red Sea, adding to challenges for global shipping through the Middle East during the Iran war.

The group said in a statement it had launched an attack on Israel and enacted a total ban on Israeli shipping in the Red Sea, warning of further escalation.

Houthi attacks on Red Sea shipping may worry energy markets more than three months into Iran's closure of the Strait of Hormuz, and with the war reigniting overnight.

LONDON, June 8 (Reuters) - More than a third of lawmakers from Britain's governing Labour Party signed a letter on Monday calling on the British government to end trade with Israeli settlements in the occupied West Bank.

Prime Minister Keir Starmer has had to balance Britain's historic position as a close ally of Israel and the United States with pressure from within his centre-left party to take a firmer line over Israeli actions towards Palestinians.

CAIRO, June 8 (Reuters) - Israeli strikes killed four Palestinians, including a child, in the Gaza Strip on Monday, health officials there said, as Israel's military expanded the area under its control, according to residents.

The reports came as mediators in Cairo said they were pressing on with efforts to salvage a fragile U.S.-brokered ceasefire deal that has ended major clashes but left many key points unresolved.

June 8 (Reuters) - U.S. President Donald Trump said on Monday that both Israel and Iran are looking to "do an immediate ceasefire", and that final negotiations on "peace" are proceeding.

"Both sides, Israel and Iran, are looking to do an immediate CEASEFIRE! Final negotiations on “Peace” are proceeding, subject to ignorance or stupidity getting in its way. The Blockade will remain in place, and in full force and effect, until a “Final Deal” is reached. Things should move quickly", Trump said in a post on Truth Social.

BEIRUT, June 8 (Reuters) - Israel has carried out nearly 3,500 air strikes on Lebanon and hundreds ofcontrolled explosions since the U.S. announced a ceasefire for the country on April 16, Lebanon's Prime Minister Nawaf Salam said on Monday.

The U.S.-brokered ceasefire came into effect just after midnight on April 17, with Israeli troops still positioned deep inside southern Lebanon. While it has largely halted air strikes on Beirut and its suburbs, it has failed to halt fighting in southern Lebanon between Israel and Iran-backed armed group Hezbollah.

MADRID, June 8 (Reuters) - Pope Leo told Spain's parliament that escalating conflict, deepening polarization and widespread disregard for human rights had pushed the world into a profound crisis, in one of his most expansive political addresses yet on Monday.

Leo, who has adopted a more forceful tone recently against the direction of global leadership, also firmly repeated his opposition to increased European military spending, urging politicians instead to end the wars ravaging the globe and help migrants.

Iran and Israel said Monday that hostilities between them had halted, after the two countries exchanged strikes that threatened to reignite the Middle East war.

Israeli Prime Minister Benjamin Netanyahu announced that the "fire on that front is contained" hours after Tehran said it had stopped its military action.

Tehran launched missiles at Israel on Sunday over Israel's ongoing war against Hezbollah in Lebanon. Israel then struck back, despite efforts by US President Donald Trump to dissuade Netanyahu.

KABUL, June 8 (Reuters) - The United Nations mission in Afghanistan has expressed concern over the arrest and detention of women in a western province for allegedly failing to comply with "dress requirements" and urged Taliban authorities to treat all people equally.

The United Nations Assistance Mission in Afghanistan (UNAMA) did not specify how many women had been affected, though local media reported last week that at least 21 women and girls were detained in Herat province.

The Afghan Taliban did not respond to Reuters request for comment.

June 8 (Reuters) - The Strait of Hormuz will be open but under new conditions to be set by Iran and Oman, including a transit fee, Iran's ambassador to Moscow was quoted as saying on Monday.

The U.S.-Israeli war on Iran has largely cut oil flows via the strait, which before the conflict saw one-fifth of the world's oil pass through. Several tankers have managed to leave the Gulf recently, but oil and liquefied natural gas flows are still severely constrained.

June 8 (Reuters) - Israel conducted strikes early on Monday against military targets in western and central Iran, hours after Iran fired a salvo of missiles at Israeli targets in retaliation for an attack on Beirut's southern suburbs.
