A deadly Israeli airstrike in Beirut kills 37 people, including Hezbollah members and leaders. The strike targeted an underground gathering of Hezbollah commanders, severely weakening their military chain of command. Cross-border violence has intensified, with Israeli warplanes launching their heaviest bombardment in southern Lebanon in 11 months and Hezbollah retaliating by targeting military sites in northern Israel. The growing violence has led to diplomatic fallout, with Lebanese Prime Minister Najib Mikati cancelling his planned visit to the UN General Assembly. The death toll in Lebanon has now surpassed 70 this week alone, making this the worst escalation between Israel and Hezbollah since their 2006 war.
