Israel-Hezbollah latest: Iran’s leader vows Tehran won’t back down as Hezbollah successor ‘targeted in Beirut’

At least one Israeli strike hit outside the perimeter of Beirut's international airport early on Friday, according to a source in Lebanon's ministry of transport and public works.

A series of loud explosions were heard near Lebanon's Beirut airport, with smoke seen nearby after jets were heard overhead, Reuters witnesses said.

Israel has a lot of options when it comes to striking back at Iran in response to its missile attacks earlier this week, the country's ambassador to the United Nations told CNN on Thursday.

"We have a lot of options ... so it's (up to) us to decide where and when we want to attack, but they are vulnerable. They know that," said Danny Danon.

The G7 statement renewed calls for an immediate ceasefire in Gaza and the leaders vowed to "continue to be in close contact with all actors" to seek to restore peace and stability.

It added: "We are also deeply concerned about the situation in Lebanon. We recall the need for a cessation of hostilities as soon as possible to create space for a diplomatic solution along the Blue Line, consistent with United Nations Security Council Resolution 1701.

"This is the only path to durably de-escalate tensions, stabilise the Israel-Lebanon border, fully restore the sovereignty, territorial integrity and stability of Lebanon, and return displaced citizens to their homes with safety and security on both sides.

"We urge all actors to protect civilian populations. We are committed to providing humanitarian assistance to address the urgent needs of civilians in Lebanon."
