Israel has hit targets across Lebanon and killed 1,030 people over the past week according to the country's Health Ministry, as Lebanese-based militant group Hezbollah sustained heavy blows to its command structure including the killing of its leader, Hassan Nasrallah.

JERUSALEM -- An Israeli airstrike on central Beirut leveled an apartment building early Monday, hours after Israel hit targets across Lebanon and killed dozens of people as Hezbollah sustained heavy blows to its command structure, including the killing of its leader, Hassan Nasrallah.

A Palestinian militant group said on Monday that three of its leaders were killed in an Israeli strike on Beirut, the first attack within city limits as Israel escalated hostilities against Iran's allies in the region.
