DOHA/RIYADH, March 19 (Reuters) - U.S. President Donald Trump said an angry Israel "violently lashed out" and attacked Iran's major gas field, a significant escalation in the U.S.-Israeli war, but ruled out further such attacks by Israel unless Iran retaliated.

Wednesday's attack on the huge South Pars gas field drove oil prices higher and prompted a threat by Iran to attack oil and gas targets across the Gulf, while it fired missiles at Qatar and Saudi Arabia.

Qatar's main gas facility has suffered extensive damage after several rounds of Iranian strikes, causing new energy supply fears as the Middle East war grinds on.

Here is a look at some of the key energy facilities that have been targeted in the US-Israel war with Iran.

- Ras Laffan -

Ras Laffan in Qatar is the world's largest liquefied natural gas (LNG) hub.

It has been repeatedly targeted by Iranian strikes since the war began, and has now suffered "extensive damage" after back-to-back waves of hits, state-run QatarEnergy said.

WASHINGTON, March 18 (Reuters) - U.S. President Donald Trump said late on Wednesday the attack on Iran's South Pars gas field was carried out by Israel, and the U.S. and Qatar were not involved in it.

Trump also said Israel would not make any more attacks on Iranian facilities in South Pars unless Iran attacked Qatar, warning that the U.S. would attack those facilities if Iran acted against Doha.

March 19 (Reuters) - The Iranian national team are continuing to prepare for the World Cup finals and have no intention of pulling out of the tournament even if they will not travel to the United States, soccer chief Mehdi Taj said on Wednesday.

Iran were one of the first nations to qualify for the finals but their participation has been in doubt since the conflict between the Islamic Republic and the United States began in late February.

The tournament runs from June 11 to July 19 and is being staged in the U.S., Mexico and Canada.

Japanese Prime Minister Sanae Takaichi sailed smoothly past a potential clash with Donald Trump over Iran on Thursday, though the US president whipped up a bit of a storm about Pearl Harbor.

Days after lashing out at US allies including Japan for failing to heed his calls to help reopen the Strait of Hormuz, Trump praised Tokyo's efforts related to the Middle East war in vague terms.

March 18 (Reuters) - Qatar's state oil giant QatarEnergy said on Wednesday that Iranian missile attacks on Ras Laffan, the site of the country's core LNG processing operations, caused "extensive damage", while the UAE shut gas facilities after intercepting missiles early on Thursday.

The attacks came hours after Iran issued evacuation warnings for several oil facilities across Saudi Arabia, the UAE and Qatar, as it prepared retaliation following strikes on its own energy infrastructure in South Pars and Asaluyeh.

Iran targeted energy facilities across the Gulf and threatened further destructive attacks after a key gas field was hit, raising fears Thursday of a wider assault on fuel supplies that could jolt already rattled global markets.

The warning came after Israel killed the Islamic republic's intelligence chief Esmail Khatib, the latest in a string of strikes that have decimated its leadership since the war began nearly three weeks ago.

Tehran, following a strike on its South Pars field, said it would respond forcefully to any further attacks on its energy sector.

WASHINGTON, March 18 (Reuters) - President Donald Trump's administration is considering deploying thousands of U.S. troops to reinforce its operation in the Middle East, as the U.S. military prepares for possible next steps in its campaign against Iran, said a U.S. official and three people familiar with the matter.

The deployments could help provide Trump with additional options as he weighs expanding U.S. operations, with the Iran war well into its third week.

WASHINGTON, March 18 (Reuters) - The Pentagon has asked the White House to approve a more than $200 billion request to the U.S. Congress to fund the war in Iran, the Washington Post reported on Wednesday, citing a senior administration official.

JERUSALEM, March 18 (Reuters) - Three Palestinian women were killed in an Iranian missile attack in the occupied West Bank late on Wednesday, the Palestinian Red Crescent said, in the first deadly Iranian strike there — and the first to kill Palestinians — since the start of the U.S.-Israeli war with Iran.

The missile struck a hair salon in the town of Beit Awwa, southwest of Hebron, the Palestinian Authority's official news agency WAFA reported. Six women were wounded, one of them seriously.
