Israeli Prime Minister Benjamin Netanyahu has vowed a severe response against Hezbollah following a rocket strike that killed 12 children in the Golan Heights. Despite Hezbollah's denial of involvement, Israel and the U.S. have placed blame on the Iran-backed group. Tensions have escalated with ongoing cross-border fire since the Gaza conflict began in October, raising fears of a broader regional war. U.S. Secretary of State Antony Blinken and other international figures are urging restraint to prevent further escalation. Israel has conducted retaliatory strikes in Lebanon, targeting Hezbollah positions. Diplomatic efforts are ongoing amidst concerns about a full-scale conflict involving Hezbollah's extensive missile arsenal and combat experience from the Syrian civil war.
