Israel's military has killed a senior member of the militant group Hezbollah in an air strike on the southern suburbs of the Lebanese capital, Beirut, despite a ceasefire, BBC reported.

It described Haitham Ali al-Tabtabai, Hezbollah's chief of staff, as a veteran of the group who had held a series of senior positions.

Lebanon's health ministry said at least five people were killed and 28 others wounded in the strike, which hit an apartment building in the densely populated Dahieh district, according to BBC.
