Hezbollah¡¯s flexible chain of command, together with its extensive tunnel network and a vast arsenal of missiles and weapons it has bolstered over the past year, is helping it endure unprecedented Israeli strikes, three sources familiar with the Lebanese militant group¡¯s operations said.

Israel¡¯s assault on Hezbollah over the past week, including the targeting of senior commanders and the detonation of booby-trapped pagers and walkie-talkies, has left the powerful Lebanese Shiite militant group and political party reeling.

On Friday, Israel killed the commander who founded and led the group¡¯s elite Radwan force, Ibrahim Aqil.
