The last residents of a Christian village on Lebanon's border with Israel fled the area on Tuesday, a U.N. source and an AFP correspondent said, after locals had for days defied an Israeli order to leave.

Fighting flared last week between Israel and Hezbollah as part of a wider regional war, prompting the Israeli military to warn people across swathes of southern Lebanon to flee.

Iran vowed on Tuesday that not one liter of oil would be exported from the Gulf while its war with the United States and Israel continues, in a stark rebuke to President Donald Trump's boast that the conflict was all but over.

Trump's argument that the war would be "ended soon" helped reverse the Monday's spike in oil prices, which have surged since Iranian attacks on shipping closed the Strait of Hormuz in response to the U.S.-Israeli strikes that killed its supreme leader.

The United Nations said Tuesday that more than 100,000 people had been newly displaced within Lebanon in just 24 hours amid the war raging in the Middle East.

"As of today, more than 667,000 people in Lebanon have now registered on the (Lebanese) government's online platform as displaced -- and this is an increase of 100,000 in just one day," said Karolina Lindholm Billing, the U.N. refugee agency's representative in Lebanon.

Iran launched new attacks on Tuesday at Israel and Gulf Arab countries as it kept up pressure on the Middle East in a war that has sent oil prices surging and stunned global economies. Five pro-Iranian militiamen were killed in an airstrike in northern Iraq.

Incoming missile sirens sounded early in the morning in Dubai in the United Arab Emirates, and in Bahrain, while Saudi Arabia said it had destroyed two drones over its oil-rich eastern region and Kuwait's National Guard said it had shot down six drones.

Israel's military said Tuesday it would soon strike Hezbollah infrastructure in the southern Lebanese cities of Tyre and Sidon, warning residents to move away from targeted buildings.

"Urgent warning to the residents of Tyre and Sidon. The IDF will soon attack military infrastructure belonging to the terrorist organisation Hezbollah," one of the military's Arabic-language spokesmen, Avichay Adraee, posted on X.

Syria said Iran-backed Hezbollah had fired artillery shells into its territory from Lebanon overnight, state media reported on Tuesday, amid the ongoing conflict between Israel and the Lebanese Shia movement.

Syrian army officials said artillery shells fired from Lebanon landed near the town of Serghaya, west of Damascus, the state news agency SANA reported on Tuesday.

Russia's President Vladimir Putin and U.S. President Donald Trump on Monday discussed the Iran war and Ukraine conflict during a "frank and constructive" telephone call, the Kremlin said.

U.S. President Donald Trump said Monday in an interview with CBS that the war with Iran was "very complete" and that the United States was far ahead of his initial timeline of around a month.

U.S. stocks jumped higher and oil prices sank in after-hours trading following Trump's comments, despite the fact that there were no immediate signs of the conflict abating.

The head of Hezbollah's parliamentary bloc Mohammad Raad vowed to continue fighting Israel "whatever the cost," on Monday, in remarks broadcast by Hezbollah's Al-Manar TV.

Hezbollah said on Monday that it had targeted the Israeli Home Front Command base in Ramla, near Tel Aviv, with "advanced missiles" as the war between the pro-Iranian group and Israel hit the one-week mark.
