WASHINGTON, March 25 (Reuters) - White House press secretary Karoline Leavitt on Wednesday said the United States is tracking "very closely" how to get oil tankers through the Strait of Hormuz.

"As far as tankers through the Strait, it's something we're tracking very closely," Leavitt told reporters about the key shipping lane near Iran. However, the press secretary said there is no "specific timeline" on when the tankers could move freely.

A fireball erupted over Gaza on Wednesday as an Israeli strike tore through a tent camp housing displaced Palestinians, killing one person and injuring seven, the territory's civil defence agency said.

The bloodshed was the latest to rock the war-shattered Palestinian territory despite a ceasefire in place since October 10.

The strike hit the Al-Sitt camp in the Deir el-Balah area, said the civil defence agency, which operates as a rescue service under Hamas.

AFP photographs showed flames engulfing the tents, sending thick black smoke into the sky.

NABATIEH, Lebanon, March 25 (Reuters) - Wearing identical uniforms, a dozen paramedics gathered around a pair of caskets in the southern Lebanese town of Nabatieh, crying so heavily their shoulders shook, as they prepared to bury two of their own killed in an Israeli strike.

US President Donald Trump insisted Wednesday that Iran was taking part in peace talks, suggesting Tehran's denials were because Iranian negotiators fear being killed by their own side.

"They are negotiating, by the way, and they want to make a deal so badly. But they're afraid to say it, because they figure they'll be killed by their own people," Trump told a dinner for Republican members of Congress.

"They're also afraid they'll be killed by us."

The US leader's comments came after Iranian Foreign Minister Abbas Araghchi said that "we do not intend to negotiate".

Here are the latest key facts about impacts from the blockage of the Strait of Hormuz, a crucial shipping route virtually paralysed by the Middle East war.

Around a fifth of global crude oil and liquefied natural gas (LNG) passes through the waterway in peacetime.

The war erupted on February 28 when the United States and Israel began bombing Iran, prompting Tehran to retaliate with strikes across the region and restrict access to the strait.

While Washington has signalled a diplomatic off-ramp from its war with Iran, Israel is preparing for the opposite in Lebanon -- an open-ended military campaign against Hezbollah.

Analysts said the message from Israel was a blunt one: Hezbollah must be disarmed, and that will take time.

"I suppose that (Israel's military) would like to have some more time to deal with Lebanon after the ceasefire with Iran," Orna Mizrahi, from the Tel Aviv-based Institute for National Security Studies, told AFP.

BRUSSELS, March 25 (Reuters) - The United Nations' refugee chief urged donors on Wednesday to provide more funds to manage the humanitarian fallout from the widening war in the Middle East, saying his agency had so far received less than 10% of the money it needs.

Thousands have been killed across the region and millions displaced in Iran and Lebanon since the United States and Israel launched strikes on Iran on February  28, prompting Tehran to retaliate with attacks on Israel, U.S. bases and Gulf states.

Filipino Defence Minister Gilbert Teodoro, whose country has declared an energy emergency as a result of the Middle East war, said on Wednesday that the Strait of Hormuz must be reopened "immediately".

Iran has virtually closed the vital strait since the US-Israeli strikes that started the war on February 28, causing global oil and gas prices to soar.

On Tuesday, Philippines President Ferdinand Marcos declared a state of "national energy emergency," citing risks to the domestic fuel supply and energy stability created by the war in the Middle East.

Israeli authorities evicted 11 Palestinian families from their homes in east Jerusalem on Wednesday, an AFP journalist reported, a move that settlers have increasingly used to occupy the vacated properties.

An AFP correspondent on the scene reported that civilians wearing high-visibility jackets were seen throwing mattresses, clothing, children's toys and other personal belongings of Palestinian families out of their homes.

Israeli rights group B'Tselem said Israeli forces had entered the Silwan neighbourhood to carry out the evictions.

Guterres told reporters he had been in close contact with many in the region and around the world and that a number of initiatives for dialogue and peace were underway.
