Following the previous day's pager explosions in Lebanon, a second wave of electronic device detonations occurred on September 18. Initial reports in the morning suggested Israel had planted explosives in 5,000 Hezbollah pagers. By afternoon, new explosions targeted walkie-talkies, mobile phones, and laptops during a funeral for victims of the first attack. Casualties rose throughout the day, with final reports indicating at least 14 dead and 450 injured. Iran and Hezbollah accused Israel and its "mercenaries" of the attacks, while the US denied involvement. The incidents led to flight cancellations to Tehran and Tel Aviv. Iran announced sending medical teams to Lebanon. International reactions poured in, with calls for UN Security Council condemnation. Hezbollah vowed a "painful response" to what it termed Israeli terrorism.
