A series of explosions in Lebanon, primarily targeting Hezbollah's hand-held radios, has left at least 20 people dead and over 450 injured, marking one of the deadliest days since hostilities with Israel resumed nearly a year ago. The blasts followed earlier detonations of Hezbollah pagers, which resulted in 12 fatalities, including two children, and thousands injured nationwide. Israeli Defence Minister Yoav Gallant indicated a new phase in the conflict with Hezbollah, while security sources allege that Israel's intelligence agency, Mossad, was responsible for the attacks. The escalating violence has raised concerns of a potential regional conflict, with Jordan's Foreign Minister accusing Israel of provoking tensions. The U.S. has denied involvement but confirmed that Israel had informed them of plans for operations in Lebanon. The situation remains chaotic, with numerous simultaneous explosions reported in various Hezbollah strongholds.
