The strike on Hezbollah’s stronghold in Lebanon's capital is a major escalation adding to fears of an all-out war.

Hezbollah did not immediately confirm the death of Ibrahim Aqeel. The United States had accused him of being involved in bombings that killed more than 200 U.S. Marines and many others in Beirut in 1983.

Israel says it has carried out an airstrike that killed a senior Hezbollah military official in a densely populated southern neighborhood of the Lebanese capital.
