Hezbollah airs slain leader Hassan Nasrallah's audio recording after his death

Hezbollah has been firing rockets and drones into Israel for more than a year in support of Hamas militants in Gaza.

Lebanese militant group Hezbollah on Sunday released an audio recording of its slain leader Hassan Nasrallah just over two weeks after an Israeli air strike killed him in southern Beirut, AFP reported.

In the recording Nasrallah is heard addressing the Iran-backed group's fighters during a military manoeuvre.

"We count on you... to defend your people, your families, your nation, your values and your dignity, and to defend this holy and blessed land and this honourable people," said Nasrallah, who was killed on September 27.

Meanwhile, Israel's military on October 14 said a Hezbollah drone killed four soldiers at one of its northern bases Sunday, as it expanded its bombardments of Lebanon and troops battled militants across the border.

The attack on a military training camp in Binyamina, near Haifa, was the deadliest such assault on an Israeli base since September 23, when Israel increased its attacks on Hezbollah in Lebanon. Emergency services reported more than 60 wounded.

Authorities in Gaza, meanwhile, said the death toll from an Israeli strike Sunday on a school being used as a shelter for displaced people had risen to 15, including whole families, while a separate overnight strike on a hospital killed four.

And as fighting raged between Israel and Hezbollah forces in Lebanon's south, United Nations peacekeepers said they had again been in the firing line.

They said Israeli troops "forcibly" entered a UN position with two tanks, after Israeli Prime Minister Benjamin Netanyahu called on the force to withdraw from the area.

Israel's military said a tank had backed into the UN post while under fire.
