F*ck with Israel and you die. Simple as that.

BEIRUT (Reuters) – Top Hezbollah commander Mustafa Badreddine was killed in an Israeli air strike at the Lebanese-Israeli border this week, the Lebanese Shi’ite group announced on Friday, the biggest blow to the group since the 2008 killing of its military commander.

Badreddine, 55, was one of the highest ranking officials in the group, according to security sources.

“He took part in most of the operations of the Islamic resistance since 1982,” Hezbollah said in a statement announcing his death, describing Badreddine as “the great jihadi leader”. He was killed on Tuesday night, the statement said.

A U.S. Department of the Treasury statement detailing sanctions against Badreddine last year said he was assessed to be responsible for the group’s military operations in Syria since 2011. Hezbollah, which is backed by Iran, is fighting in Syria in support of President Bashar al-Assad.

Badreddine, a brother-in-law of the late Hezbollah military commander, Imad Moughniyah, was indicted by the U.N.-backed Special Tribunal for Lebanon in the 2005 killing of statesman Rafik al-Hariri.
