Lebanon's civil defence agency said at least seven other people were wounded in the Dahiyeh area, according to Al Jazeera and AFP. BBC News also reported Lebanon's statement that three people were killed in an Israeli strike on a Beirut suburb.
The casualty figure is Lebanese official reporting, not an independently verified toll. The target description is Israeli official reporting: Al Jazeera reported that Prime Minister Benjamin Netanyahu's office said the military struck Hezbollah targets in Dahiyeh in response to firings by Hezbollah towards Israeli territory.
The Israeli military said Hezbollah launched three projectiles towards northern Israel and described that fire as a ceasefire violation, according to Al Jazeera. Hezbollah's full account of the projectiles was not available in the sources reviewed for this draft.
The Beirut strikes came during a fragile regional diplomatic track. Al Jazeera reported that the latest escalation raised concern about talks between the United States and Iran, and quoted United Nations Secretary-General Antonio Guterres as condemning the strikes and urging restraint while US-Iran diplomacy continued.
Iranian officials framed the strikes as relevant to those talks. Al Jazeera reported that Foreign Ministry spokesman Esmaeil Baghaei said a deal was close but would not be signed on Sunday, and that Mohammad Bagher Ghalibaf, Iran's top negotiator and parliamentary speaker, said the attacks showed Washington either lacked the will or the ability to fulfil commitments.
Al Jazeera also reported that a Qatari delegation was in Tehran working to narrow disputes between Washington and Tehran. That gives the Beirut strike a diplomatic setting beyond Lebanon, but it does not establish that the strike alone changed the outcome of the negotiations. The available sources support a narrower statement: several officials and observers treated the Lebanon escalation as a risk to talks already in progress.
Israel's stated rationale is narrower. Netanyahu's office tied the attack to Hezbollah fire towards Israeli territory, and the Israeli military cast the three projectiles as a breach of the ceasefire, according to Al Jazeera. That counter-position matters because the dispute turns on whether each side treats Lebanon as covered by the same diplomatic de-escalation effort as the US-Iran track.
