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.

Fatah Sharif had been placed on administrative leave since allegations of his ties to the militant group emerged in March.

Hours before Hezbollah's Qassem spoke, Hamas said an Israeli airstrike killed its leader in Lebanon, Fateh Sherif Abu el-Amin, along with his wife, son and daughter in the southern city of Tyre on Monday.
