Hezbollah's commander-in-chief Ibrahim Aqil was killed in the bombing of Beirut, Lebanon.
A multi-storey building has been torn down by an Israeli airstrike in Beirut, where aqil is reported to be among the dead.
"The Israeli airstrike killed the commander of the 'Radwan' Forces Ibrahim Aqil, the second commander of its armed force after Fuad Shukr," who was killed by an Israeli strike in July, also in hezbollah's southern stronghold of Beirut, several official sources told Israeli media.
Tensions between Israel and Hezbollah have been rising sharply for days after Mossad allegedly carried out an electronic attack by detonating thousands of communication devices held by Hezbollah militants, which ended in a balance sheet of about 20 deaths and several thousand wounded.
Izral has carried out a campaign of air bombing of "Hezbollah targets" in Lebanon since Yesterday.
