UNIFIL, the UN peacekeeping force in Lebanon, expressed deep concern over heightened tensions after a presumed Israeli strike killed Hamas's deputy leader in Beirut. The strike, marking an escalation in the Israel-Hamas conflict, occurred in a Hezbollah stronghold. Hamas confirmed the death, attributing it to an Israeli drone strike. Hezbollah warned of retaliation, vowing the act wouldn't go unanswered. This incident, the first strike in Beirut since hostilities began, raised fears of further escalation in the region.
