The Israeli military announced Saturday that an airstrike it launched in Lebanon has killed Hassan Nasrallah, the man who led Hezbollah for more than three decades and built it into a fearsome terrorist organization.

Nasrallah was killed Friday when Israel bombed a complex where Hezbollah leadership was meeting near Beirut, Israeli officials said.

Other Hezbollah leaders, including Ali Karki, the commander of its Southern Front, were also killed in the attack, Israel said.

Hezbollah did not immediately confirm the deaths. But the Lebanese Health Ministry said that six people were killed and 91 injured in the strikes.

Nasrallah has led the Iran-backed Hezbollah since 1992 during an era when it has engaged in significant hostilities with Israel and conducted terrorist attacks across the globe.

The United States designated Hezbollah as a foreign terrorist organization in 1997 under then President Bill Clinton.

Hezbollah is a “political, military, and terrorist organization capable of conducting attacks worldwide,” the Director of National Intelligence says on its site of designated terrorist organizations.
