Thousands of people attended the funeral organized by the militant Hezbollah group on Monday for its top military commander a day after he was killed in an Israeli airstrike on a southern suburb of Beirut.

Supporters walked by Haytham Tabtabai’s coffin, draped in the group’s yellow flag, as it was carried through the crowd.

The burial of Tabtabai and two other members took place in a cemetery south of Beirut where Hezbollah fighters are traditionally laid to rest.

Israel on Sunday struck Lebanon's capital for the first time since June, saying it killed Tabtabi whom the Israeli military described as Hezbollah's chief of staff.

Israel also warned the Iran-backed militant group not to rearm and rebuild a year after their latest war.

The strike in Beirut’s southern suburbs killed five people and wounded 25 others, Lebanon’s Health Ministry said.
