The leader of Hezbollah has said Israel’s mass attacks on electronic devices in Lebanon could have killed “thousands,” that it crossed “all red lines,” and was a “declaration of war”.

Israel carried out one of the most intense bombardments of the past year, as warplanes launched 70 airstrikes, Lebanese security officials said. The barrage came shortly after Hezbollah’s leader vowed to respond after explosions of pagers and walkie-talkies killed at least 37 people.

A source close to Hezbollah in Lebanon said an Israel air strike Friday killed one of its top military leaders, with Israel confirming it had carried out a "targeted strike"
