Israel launched a wave of strikes on Tehran and Beirut on Tuesday while attacks in Baghdad drew neighbouring Iraq deeper into the Middle East war that has sparked economic turmoil across the globe.

The Iranian capital, under near-daily bombardment since a joint US-Israeli attack started the war on February 28, was hit by what the Israeli military said were strikes on "terror regime infrastructure".

Lebanese state media reported on Tuesday that Israeli strikes at dawn hit a residential building in Beirut's southern suburbs, a stronghold of the pro-Iranian armed group Hezbollah.

Authorities in Lebanon said more than one million people have registered as displaced since March 2, with more than 130,000 people staying in upwards of 600 collective shelters.

A drone and rocket attack targeted the US embassy in Baghdad early on Tuesday, while a strike killed four people at a house reportedly hosting Iranian advisers.

The strikes on the embassy complex came hours after air defences had thwarted a rocket attack and a drone sparked a fire at a luxury hotel frequented by foreign diplomats in Baghdad's fortified Green Zone.

Qatar said it had intercepted a missile attack, with a journalist saying he heard several explosions in Doha on Tuesday, a day after similar blasts were heard across the Qatari capital.

Qatar, like several other Gulf nations, has been targeted by both drones and missiles in recent days.

In nearby Dubai, three explosions were also heard after a mobile phone alert warned residents of the United Arab Emirates' most populous city to "immediately seek a safe place" over "potential missile threats".

A new drone strike hit the Fujairah oil complex on the UAE's east coast on Tuesday, causing a fire but no injuries. But falling shrapnel from an intercepted missile killed a Pakistani national in Bani Yas, Abu Dhabi.

Iran has fired more than 1,900 missiles and drones at the UAE, more than any other country targeted by Tehran since the start of the Middle East war.

The war has now engulfed the region, with Iran striking at least 10 countries that host US forces and its Revolutionary Guards saying it had fired around 700 missiles and 3,600 drones.

More than 1,200 Iranians have been killed by US and Israeli strikes, according to the last toll from Iran's health ministry on March 8. (AFP)
