Israel launched a series of strikes in Lebanon early on Saturday, the Israel Defense Forces (IDF) said.

"The IDF has begun striking Hezbollah infrastructure sites in Beirut," the military said in a statement on Telegram.

Lebanon's National News Agency (NNA) reported an Israeli drone attack that caused two deaths in the south of the country.

The Lebanese Health Ministry reported 11 people injured in overnight Israeli air attacks in the south. A hospital had been damaged, it said.

There was no immediate comment from the Israeli military on either report.

Eyewitnesses in Beirut reported a total of seven Israeli attacks in the capital's densely populated southern suburbs, an area seen as a stronghold of the Iranian-backed Hezbollah militia. There were no initial reports of casualties.

The Israeli military has repeatedly called on the population to leave the area.

Air-raid warnings were heard in northern Israel early on Saturday after Hezbollah fired projectiles. Israeli media reported damage to cars and houses from a rocket exploding near the border.

Hezbollah claimed responsibility for a number of attacks.

The Israeli military has also accused Hezbollah of being responsible for an attack on Friday on a UN military observer post in which three soldiers were wounded, some of them seriously.

The United Nations Interim Force in Lebanon (UNIFIL) mission has been monitoring the border region since 1978.

Rockets fired on Israel from Iran

The Israeli military also reported multiple rocket attacks from Iran overnight.

"Search and rescue forces, both reserve and regular forces, are on their way to sites in central Israel where reports of impact have been received," the IDF said.

Explosions reported in Tehran

Meanwhile in Tehran, residents in the north and west of the city reported explosions.

Attacks around The Gulf

In retaliation for the US-Israeli attacks launched on February 28, Iran has also targeted Gulf countries it considers US allies.

Overnight, residents in Bahrain were urged to seek shelter while in Dubai debris from aerial interceptions fell onto the facade of buildings in two separate incidents. There were no reported injuries, officials said.
