Exchanges are intensifying between Israel and Hezbollah after the explosions of thousands of Hezbollah devices in Lebanon.
Israel said Friday it had pounded the Iran-backed militant group in overnight strikes, just hours after the group's leader vowed retribution for the blasts that targeted its communication devices.
A source close to the movement later said a top military leader was among several killed in a strike on Beirut, which Israel said was "targeted".
