A significant number of members from the Lebanese armed group Hezbollah, including both fighters and medical personnel, sustained serious injuries on Tuesday due to the explosion of their communication pagers, according to a security source who spoke to Reuters.

An anonymous Hezbollah official described the incident as the “largest security breach” the organization has experienced in nearly a year of conflict with Israel. A Reuters reporter observed ambulances navigating through the southern suburbs of Beirut amidst widespread chaos, with residents reporting that explosions continued to occur even 30 minutes after the initial detonations.

Groups of individuals gathered at building entrances to inquire about the well-being of acquaintances who might have been injured, as noted by the Reuters journalist.

The security source also mentioned that similar devices were detonating in southern Lebanon. The Israeli military has not provided an immediate response, despite ongoing exchanges of fire with Hezbollah since last October, coinciding with the conflict in Gaza.
