Lebanon's Hezbollah will bury its former leader Hassan Nasrallah on Sunday nearly five months after he was killed in an Israeli airstrike, in a mass funeral aimed at showing political strength after the group emerged badly weakened from last year's war.

Axar.az reports that citing Reuters, the funeral in Beirut's southern suburbs will also honour Hashem Safieddine, who led Hezbollah for one week after Nasrallah's death before he was also killed by Israel. He will be buried in the south on Monday.

The ceremony will be held at Lebanon's biggest sports arena - Camille Chamoun Sports City Stadium on the outskirts of the Hezbollah-controlled southern suburbs.

Nasrallah will then be buried at a dedicated site nearby.

Nasrallah was killed on September 27 in an Israeli airstrike as he met commanders in a bunker in Beirut's southern suburbs, a stunning blow in the early phase of an Israeli offensive that has left the Iran-backed group a shadow of its former self.
