The strikes Friday "on Haret Hreik in Beirut's southern suburbs led to the death... of six people and the wounding of 91", a ministry statement said, raising an earlier toll of two dead and 76 wounded.

"Rubble is still being removed" from the site, it added.

Hezbollah's Al-Manar television said late Friday that the amount of rubble was hampering efforts to find survivors.

The Israeli military said it "carried out a precise strike on the central headquarters" of Hezbollah, which it said was "located under residential buildings in the heart of Dahiyeh", referring to Beirut's southern suburbs.

Al-Manar said seven residential buildings were destroyed in the targeted area, while Hezbollah cordoned off the site and told journalists to move away.
