An initial investigation by Lebanese authorities has revealed that hand-held devices that exploded earlier this week were booby-trapped before entering the country, Lebanon's mission to the United Nations reported. The devices, rigged to detonate via emails, targeted users linked to Hezbollah. The attacks, which killed 37 people and wounded nearly 3,000, have been described as 'unprecedented in their brutality' and have further destabilized Lebanon. The conflict has escalated tensions on Israel's northern border, with hundreds of Hezbollah fighters and dozens of Israeli soldiers killed in the exchanges.
