Israel bombarded Lebanon on Monday, expanding conflict across the region after the massive Israel-US attack on Iran.
Israeli forces pounded targets across Lebanon, including Beirut’s southern suburbs, after Hezbollah fired rockets towards Israel in retaliation for the killing of Iran's supreme leader Ali Khamenei.
US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu have urged Iranians to overthrow the government in Iran.
In a video address, Trump urged Iranian security forces "to lay down your arms and receive full immunity or face certain death."
"It will be certain death," he repeated. "It won't be pretty."
As the American and Israeli airstrikes kept hitting the country, top Iranian security official Ali Larijani said on X: “We will not negotiate with the United States.”
Iran's first retaliatory strikes on Saturday hit all the Gulf states apart from mediator Oman.
On Sunday, Oman's commercial port of Duqm was hit by two drones, injuring a foreign worker, the Oman News Agency said.
Three ships were also attacked in the Strait of Hormuz on Sunday after Iran had previously declared the strategic waterway was closed, sending global oil prices spiking.
The Revolutionary Guards claimed to strike the aircraft carrier USS Abraham Lincoln, but the Pentagon said the "missiles launched didn't even come close."
Trump said that US military strikes had sunk nine Iranian naval vessels and partially destroyed its navy headquarters.
Iran's retaliatory strikes in the Gulf have killed at least four people and wounded dozens of others.
More than 200 people have been killed since the start of the strikes that killed Khamenei and other senior leaders, Iranian leaders have said.
