"These are preliminary findings, based on initial physical evidence," UN spokesperson Stephane Dujarric told a news briefing, adding that a full investigation process was continuing that included engagement with the parties concerned.

After more than a month of blistering attacks by the United States and Israel, Iran said it had agreed to talks with Washington to begin Friday in Pakistan on a path to end the conflict.

"An attack caused a fire at the SABIC plants in Jubail. The sounds of explosions were very loud," the source told AFP, referring to the Saudi Basic Industries Corporation.  

Iran effectively closed the vital sea route, a corridor that carries a fifth of global oil and liquefied natural gas flows, in response to US and Israeli airstrikes that began in late February.

Calls are mounting for a thorough review of Indonesia’s peacekeeping deployment to Lebanon following last week’s fatal incidents, with some urging a full suspension of the mission as ongoing Israeli attacks continue to claim lives and heighten risks for troops on the ground. 

In a statement, UNIFIL said it was "extremely concerned" about attacks from both sides "carried out from near our positions, which could potentially draw return fire".

Reuters could not immediately verify the report. The White House and the US State Department did not immediately respond to Reuters' requests for comment. 

The Indonesian Military (TNI) is open to the possibility of reducing the number of peacekeepers deployed to Lebanon next month, as more Indonesian blue helmets were injured in the southern part of the country amid the escalating conflict in the Middle East.

The statement came after US President Donald Trump said on Sunday that the officer had been rescued in a search and rescue operation and was "SAFE and SOUND".

Inside the Holy Sepulchre, the celebrations were being held behind closed doors in front of a very small congregation, a far cry from the crowds that usually gather.

Since the start of the Israel-Hezbollah war on March 2, the UN Interim Force in Lebanon (UNIFIL) has been caught in the crossfire in the country's south, with Hezbollah launching attacks on Israel and its troops, and Israeli forces pushing into border towns.

Kuwait and Israel said their air defences were responding to the latest attacks from Iran, part of the war that erupted more than a month ago with US-Israeli strikes that triggered retaliation by Tehran.

After the latest attack that injured three more soldiers, Indonesian Military (TNI) Commander Gen. Agus Subiyanto ordered Indonesian peacekeepers in Lebanon to enter bunkers and refrain from activities outside.

The government urged the United Nations Security Council to hold a meeting between UNIFIL-contributing countries to take measures to enhance the protection of personnel serving with the peacekeeping force.

A meeting of the Council's 15 members was initially set for Friday before being rescheduled for Saturday, but several diplomats later said it had now been postponed until next week, with no new date yet announced.

A blast took place inside a UNIFIL facility near El Adeisse on Friday afternoon local time, injuring three Indonesian peacekeepers, two of whom were seriously wounded.

The prospect of a US service person being alive and on the run inside Iran raises the stakes for Washington in a conflict with low public support and no sign of an imminent end.

Just 221 commodities vessels have crossed the Strait of Hormuz since March 1, some more than once, down from around 120 daily transits during peacetime.

Indonesia’s participation in the United States-led Board of Peace (BoP) is facing growing domestic opposition, with a recent national survey showing most Indonesians disapprove of joining US President Donald Trump’s initiative and deploying troops amid the escalating US-Israeli war against Iran.

Indonesia’s major Islamic organizations have expressed solidarity with Iran, backing the country’s call for a unified response to what it describes as military aggression by the United States and Israel, and urging a swift end to the conflict as tensions in the Middle East escalate.

Indonesia is coordinating closely with the United Nations to repatriate the bodies of three Indonesian peacekeepers killed in Israeli strikes in southern Lebanon last week, the Foreign Ministry has confirmed, with the remains expected to return home in the next few days.

"The Iranian Foreign Minister assured the (Foreign) Secretary that Iran will allow the safe, unhindered, and expeditious passage through the Strait of Hormuz of Philippine-flagged vessels, energy sources, and all Filipino seafarers," the foreign affairs department said in a statement.

Munir has had several meetings with President Donald Trump, including an unprecedented one-on-one lunch at the White House, while the government has apprehended an Islamic State bomber accused of killing American troops and handed him over to the US.

Under the law, passed in parliament on Monday, Palestinians in the occupied West Bank convicted by military courts of carrying out deadly attacks classified as "terrorism" will face the death penalty as a default sentence.

In an evening speech from the White House, Trump broke little new ground on how the war would end and vowed two to three weeks further of "extremely hard" strikes against Iran.

As Israel’s military offensive in Lebanon intensifies, Farizal Rhomadhon’s family in Kulon Progo, Yogyakarta, mourns the sudden loss of the peacekeeper, whose last call with his father ended abruptly before his death.

"We will not pay any toll as what may have been misunderstood by some netizens online. We're not paying anything," Fahmi Fadzil, who is also communications minister, told a regular press conference.

The two countries outlined a joint initiative "for restoring peace and stability in the Gulf and Middle East region", after a visit from senior Pakistani officials to Beijing.

The two peacekeepers with the UNIFIL force were killed on Monday near Bani Hayyan in south Lebanon and two other soldiers were wounded. Another Indonesian soldier was killed overnight Sunday into Monday when a projectile exploded near one of the group's positions.

Two other Indonesian UNIFIL were killed in southern Lebanon on Monday, one day after another peacekeeper died in an explosion amid the intensifying Israeli ground invasion.
