Youssef Assaf was in a Lebanese Red Cross ambulance when it was targeted by an Israeli strike near Tyre, in southern Lebanon. The 35-year-old paramedic died of his wounds two days later.

"I was called around 10:30 pm and told that he was wounded and in the hospital," his wife, Jeanne d'Arc Boutros, told AFP from northern Lebanon, where she had fled to a relative's home.

"I knew my husband is strong and can endure. I didn't react at all -- I just kept praying and repeating in my heart that nothing bad would happen to him," the 32-year-old schoolteacher said.

DUBAI, March 17 (Reuters) - Iran arrested 10 foreigners among dozens rounded up on suspicion of collaborating with Israel and the U.S., Iranian media said on Tuesday, as officials warned people to stay at home during a festival that they said could be exploited by "the enemy".

Iran's police chief Ahmadreza Radan said on Sunday that at least 500 people had been arrested since the start of the war pitting Tehran against Israel and Washington, accusing the detainees of sharing information with adversaries.

CAIRO, March 17 (Reuters) - An Israeli airstrike killed at least three people including a child in the Gaza Strip on Tuesday, local health authorities said, the latest violence jeopardising the ceasefire which has been under strain during the Israeli-U.S. war against Iran.

Medics said the airstrike targeted a vehicle in the western area of Khan Younis, south of the enclave, killing three people, including a child, and wounding 12 other people. There was no immediate Israeli comment.

DAMASCUS, March 17 (Reuters) - Syrian authorities have banned alcohol from restaurants and bars in Damascus, one of the clearest moves yet by the Islamist-led government towards enforcing conservative ways since Ahmed al-Sharaa toppled Bashar al-Assad 15 months ago.

The decree, issued by the Damascus governorate on Monday evening, requires that nightclub and bar licences be converted into café licences and restricts the sale of alcohol to sealed bottles for takeaway and only in predominantly Christian areas.

No explosions, few police checks and well-stocked shops: in the relaxed Caspian Sea resorts where many Tehran residents have fled, the ongoing war seems far away.

"It seems as though people barely realise that there's a war happening," said an Iranian woman in her thirties, who decamped there from the capital.

"Or they are not paying much attention to it," added the woman, who agreed to be interviewed by AFP on condition of anonymity.

LONDON, March 16 (Reuters) - As the U.S.-Israel war with Iran enters its third week, analysts warn it is severely disrupting fertiliser markets and endangering food security for developing countries in the near term.

Here is how the conflict is affecting fertiliser costs, trade flows and output:

WHY IS THE HORMUZ STRAIT KEY FOR FERTILISER SUPPLY?

Fertiliser production is energy-intensive, relying heavily on natural gas as a feedstock, with energy making up as much as 70% of production costs.

From sea turtles to birds and the gentle dugong, the Persian Gulf's diverse but fragile marine life is threatened by the bombs and oil of the war in the Middle East.

The ecosystem was already under pressure from climate change and maritime traffic before the United States and Israel launched their war on Iran at the end of February, leading to Tehran's region-wide retaliation.

WARSAW, March 17 (Reuters) - Poland will not send troops to Iran as the conflict does not directly affect its security, Prime Minister Donald Tusk said on Tuesday, adding that the United States and other powers understood Warsaw's decision.

U.S. President Donald Trump called on allies over the weekend to help secure the Strait of Hormuz as Iranian forces continue attacks on the vital waterway amid the U.S.-Israeli war on Iran, now in its ​third week.

WASHINGTON, March 17 (Reuters) - The Trump administration is seeking other sources of fertilizer amid the ongoing Iran war's shipping constraints, including from Venezuela and possibly Morocco, White House economic adviser Kevin Hassett said on Tuesday.

"We've ... established licenses for Venezuela to produce more fertilizer. We've had discussions with Morocco," he said on CNBC's "Squawk Box" program, calling it "an insurance policy against disruption" for U.S. farmers.

GENEVA, March 17 (Reuters) - Israeli airstrikes on residential buildings, displaced people and healthcare workers in Lebanon raise concerns under international law and may amount to war crimes, the United Nations human rights office said on Tuesday.

The Israeli military has been carrying out airstrikes in Lebanon since the Iran-backed Shi'ite Muslim group Hezbollah fired rockets at Israel from Lebanon early in the U.S.-Israeli war against Iran.
