From Grok;

On May 6, 2026 (today), Israel carried out a strike on a building in Haret Hreik, a densely populated neighborhood in Beirut’s southern suburbs (Dahieh). This was the first Israeli strike on Beirut proper since the US-brokered ceasefire took effect on April 16–17, 2026 (initially for 10 days and later extended).

Israeli perspective (confirmed by officials):Israeli Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz publicly approved and claimed responsibility. They stated the target was Malek Ballout (also spelled Balut/Ballout), a commander in Hezbollah’s Radwan Force, along with other militants in the building. Israel alleges he directed attacks on Israeli communities and soldiers, violating the ceasefire. Some reports indicate coordination with the US and possible naval launch (three missiles from a warship).
