CAIRO/JERUSALEM, March 2 (Reuters) - Gaza is rapidly running out of its limited fuel supply and stocks of food staples may become tight, officials say, after Israel blocked the entry of fuel and goods into the war-shattered territory, citing fighting with Iran.

Israel's military closed all Gaza border crossings on Saturday after announcing air strikes on Iran carried out jointly with the United States. Israeli authorities say the crossings cannot be operated safely during war and have not said how long they would be shut.

KAPIKOY, Turkey, March 2 (Reuters) - Hundreds of Iranians crossed the border into Turkey on Monday afternoon as the U.S.-Israeli war against Iran expanded, a Reuters witness said, with those arriving speaking of fear in Tehran and queues at petrol stations.

WASHINGTON, March 2 (Reuters) - U.S. Defense Secretary Pete Hegseth said on Monday that military operations against Iran would not lead to an "endless war" and that the aim was to destroy Tehran's missiles, Navy and other security infrastructure.

"We're hitting them surgically, overwhelmingly and unapologetically," Hegseth said during a press conference at the Pentagon.

PESHAWAR, March 2 (Reuters) - Pakistan sent the military into Himalayan Gilgit-Baltistan region on Monday and banned large gatherings nationwide after deadly protests against U.S. and Israeli strikes on Iran spread, with 26 dead so far.

In the northern city of Skardu, in Shi'ite majority Gilgit-Baltistan, normally a tourist hotspot, protesters set fire to a U.N. office on Sunday with 14 people, including a soldier, killed in the ensuing clashes, local officials said. Two others died in the capital Islamabad.

KYIV, March 2 (Reuters) - A new round of U.S.-brokered peace talks between Ukraine and Russia, scheduled for week, has not been canceled following the weekend strikes on Iran by the U.S. and Israel, Ukrainian President Volodymyr Zelenskiy said on Monday.

Zelenskiy said that Kyiv was considering a new location for the talks, which had been due to take place on March 5 and 6 in Abu Dhabi, and that Turkey or Switzerland were possibilities.

As drones swarmed the skies above Iraq's Erbil and air defences streaked up to shoot them down, residents watched from below, fearing the fire would soon reach them.

Iraq's autonomous Kurdistan region hosts US-led coalition troops, and its capital, Erbil, is home to a major US consulate complex, making it a target of the war in the Middle East, triggered by the joint US-Israeli strikes Saturday on Iran.

For days, loud bangs have been heard in Erbil as US air defences repeatedly intercepted drones.

MOSCOW, March 2 (Reuters) - Russian President Vladimir Putin told UAE President Mohammed bin Zayed Al Nahyan in a phone call on Monday that he was ready to relay his complaints about Iranian strikes against UAE territory to Tehran, the Kremlin said.

It cited the UAE leader as saying that his country was not being used as a base to attack Iran and that Iranian strikes on the UAE could not therefore be justified.

As Israeli strikes shattered the nighttime quiet, Beirut cafe owner Hassan rushed home to whisk his wife and young daughter to safety in the nearby mountains outside the city.

The sound of heavy gunfire was a warning to residents that war had returned. The roads quickly clogged and the trip took Hassan, 30, and his family more than three hours.

"We rushed out without taking anything with us, no clothes and no food for my daughter," he said.
