Dubai | US President Donald Trump said Monday he has demanded that about seven countries send warships to keep the Strait of Hormuz open as fears of a global energy crisis persist. Iranian strikes on commercial ships in and around the strait, and even just the threat of attacks, have slowed shipping there to a trickle.

The US and Israel have kept pummeling what they describe as military targets in Iran's capital, and Israel stepped up its campaign against Iran-backed militants in Lebanon. More than 1 million people have been displaced in Lebanon - roughly 20 per cent of the nation's population - as UN peacekeepers say Israel is massing ground troops along the border.

Iran has retaliated with persistent drone and missile attacks on neighbouring countries, including oil fields in Iraq and the United Arab Emirates, where a drone strike temporarily closed Dubai's airport, a crucial travel hub.

The war has killed at least 1,300 people in Iran, at least 880 in Lebanon and 12 in Israel, according to officials in those countries. The US military says 13 US service members have been killed and about 200 wounded.

Here is the latest:

Drone footage appears to show the US Embassy in Baghdad Footage released Tuesday by a pro-Iran Shiite militia in Iraq appears to show the US Embassy in Baghdad, one of the country's most secure facilities.

The footage came from Saraya Awliya al-Dam, or "Companies of the Guardians of Blood," a group that has claimed several attacks since the start of the Iran war.

The footage, dated Monday and shot from a quadcopter, showed the drone swooping over the complex.

Details of the facility in the footage, including an American flag at the compound, corresponded to satellite pictures and known features of the complex.

The footage ends without showing any attack by the drone.

This marks the second "first-person-view" drone footage coming from militias in Iraq during the war.

The first was an attack on an American facility at Baghdad International Airport.

Such footage has become common in Russia's years-long war on Ukraine.

A tanker hit off the coast of the UAE

A tanker anchored off the UAE's eastern coast was hit by a projectile early Tuesday morning as the nation came under several waves of Iranian attacks.

The United Kingdom Maritime Trade Operations centre, run by the British military, reported the attack, saying the vessel was in the Gulf of Oman off Fujairah.

It said the tanker sustained "minor structural damage" and no one was hurt.

Since the Iran war started, some 20 vessels in the region have come under attack as Iranian fire effectively halts traffic through the Strait of Hormuz, the narrow mouth of the Persian Gulf through which 20 per cent of all oil and natural gas traded passes.

Shrapnel from shot-down drones hits the US Embassy in Baghdad Incoming fire targeted the US Embassy in Baghdad early Tuesday, with the facility's air defences shooting down the projectiles, two security officials said.

The Iraqi officials, who spoke on condition of anonymity to discuss intelligence matters, said the embassy's C-RAM air defence shot down all four drones targeting the facility.

However, shrapnel hit the embassy.

The C-RAM, or counter rocket, artillery, and mortar system, sprays 20 mm rounds on incoming fire targeting the facility.

Separately, an apparent airstrike targeted a house in the heavily fortified presidential compound in Baghdad's al-Jadriya area, the officials said.

It wasn't clear who carried out that attack.
