At a church in the mountains outside Beirut, Raymonda Mouawad raged as she buried her brother, killed by an Israeli strike in a war against Hezbollah that he had nothing to do with.

"We shouldn't be forced to bear the guilt of others' mistakes," she said, her voice filled with anger and sorrow.

"We're done with Israel and Hezbollah. That's all I want to say," she told AFP at the church, which was overflowing with hundreds of family members, friends and supporters.

Donald Trump's increasingly apocalyptic threats of destruction in Iran have raised concerns of just how far the US president might go militarily to bend the Islamic republic to his will.

Trump announced Tuesday that "a whole civilization will die" if Iran does not heed his ultimatum to accept US war demands, while Vice President JD Vance warned that Washington had additional "tools in our toolkit" that could be deployed against Tehran.

- New 'tools' -

LISBON, April 7 (Reuters) - Portugal said it had authorised 76 landings by U.S. aircraft at the Lajes air base in the Azores and 25 overflights of its territory since the start of the U.S.-Israeli war on Iran, on condition they were not used to bomb civilian infrastructure.

Foreign Minister Paulo Rangel told a parliamentary hearing the U.S. had complied with the condition, in the spirit of "loyal cooperation" between the two NATO allies, but said that on several occasions landings had also been refused.

US President Donald Trump has threatened to destroy Iran's power stations and bridges, but bombing electricity plants would likely spur a humanitarian crisis and fierce retaliation from Tehran, experts say.

- What could be targeted? -

Previous airstrikes from the United States and Israel during the more than five-week war have hit energy infrastructure such as gas production facilities or oil depots, as well as transport routes.

April 7 (Reuters) - Iran wants to charge fees for ships to pass through the Strait of Hormuz as part of its proposals to end the war with Israel and the United States after blocking most traffic through the crucial energy waterway for weeks.

The Strait, a strip of water only 34 km (21 miles) wide between Iran and Oman, provides passage from the Gulf to the Indian Ocean and is the main route for about a fifth of world oil supplies and other vital goods including fertilisers.

WHAT IS IRAN PROPOSING?

Iraq's powerful armed group Kataeb Hezbollah on Tuesday released US journalist Shelly Kittleson, a week after she was kidnapped in Baghdad, the Iranian-backed group and the United States said.

Her release was announced hours before the United States and Iran agreed to a ceasefire in more than one month of war, which spread into a regionwide conflict.

April 7 (Reuters) - At a vote in the U.N. Security Council on Tuesday, China and Russia vetoed a Bahraini resolution encouraging states to coordinate efforts to protect commercial shipping in the Strait of Hormuz.

The 15-member Security Council voted 11 in favor of the resolution, with two against - China and Russia - and two abstentions.

"The draft resolution has not been adopted, owing to the negative vote of a permanent member of the Council, Bahrain's Foreign Minister Abdullatif bin Rashid Al Zayani told the Council.

Russia and China vetoed a UN Security Council resolution Tuesday on reopening the Strait of Hormuz, a text already diluted to remove Gulf states' desired green light to use force to protect the key shipping lane.

The draft resolution prepared by Bahrain and supported by the United States received 11 votes in favor, two against and two abstentions. Bahrain's Foreign Minister Abdullatif bin Rashid Al Zayani said Gulf states "regret" the outcome.

Flooding the internet with posts from embassies across the world, sharing Lego videos mocking Donald Trump and even maintaining live accounts in the name of its slain supreme leader -- Iran has charged headlong into the battlefield of social media.

Five weeks into the war against Israel and the United States, Iranian authorities have pulled out all the stops to aggressively promote the Islamic republic's narrative online.

Two French nationals headed home from war-stricken Iran on Tuesday after spending more than three years in an Iranian prison on espionage charges, authorities said.

Cecile Kohler, 41, and Jacques Paris, 72, were due back in France on Wednesday, Foreign Minister Jean-Noel Barrot said as he hailed their departure from the country facing US threats of devastating attacks.

The couple had been under house arrest at the French embassy in Tehran since they were freed in November.
