The Israeli military said it has struck 300 targets in Lebanon as it steps up the pressure on the Hezbollah militant group.

The army announced the strikes on the social media platform X, posting a photo of what is said was the military chief, Lt Gen Herzi Halevi, approving additional attacks from military headquarters in Tel Aviv.

It is one of the most intense barrages of air strikes in nearly one year of fighting against Hezbollah.

Lt Gen Halevi and other Israeli leaders have promised tougher action against Hezbollah in the coming days.

As Israel was carrying out the attacks, Israeli authorities reported a series of air-raid sirens in northern Israel warning of incoming rocket fire from Lebanon.

Earlier, Israel had urged residents of southern Lebanon to leave their homes in areas where it claims Hezbollah has stored weapons, warning of “extensive strikes” there.
