Hezbollah fighters are prepared to counter any Israeli ground invasion of Lebanon, said the group's deputy leader Naim Qassem on Monday in his first public speech since Israeli airstrikes killed its veteran chief, Hassan Nasrallah, last week.
The latest development comes as Israel continued its ariel bombardment of Lebanon on Sunday, killing at least 105 people, with airstrikes hitting the centre of the capital Beirut on Sunday night.
The airstrikes, which previously concentrated on the southern Dahiyeh suburb of Beirut, but on Sunday hit the Kola area within Beirut city's administrative boundaries, killing three leaders of the militant group the Popular Front for the Liberation of Palestine.
Another Israeli airstrike on a Palestinian refugee camp in the south of the country killed Hamas's leader in Lebanon, Fateh Sherif Abu Al-Amin.
Israel continues to conduct relentless attacks in southern Lebanon and in the Bekaa valley, where an Israeli airstrike killed five paramedics in Sahmar.
On Sunday Israel also struck the Yemeni port of Hodeidah, killing at least four people, following the launch of missiles and drones at Israel by the Houthis.
Israel has rejected any attempts to reach a ceasefire, with Foreign Minister Israel Katz saying that the government would only accept a ceasefire with Hezbollah moving north of the Litani river and the group being disarmed, according to Israel's public broadcaster Kan.
