Tensions between Israel and Hezbollah have escalated following a deadly rocket strike in the Israeli-occupied Golan Heights that killed 12 children. Israel retaliated by hitting multiple Hezbollah targets in southern Lebanon, killing one fighter and injuring civilians. Israeli Prime Minister Netanyahu has vowed a severe response, raising fears of a broader conflict that could involve the U.S. and other regional players. The Biden administration and other international figures, including Italy's Prime Minister Giorgia Meloni, are urging restraint to prevent a full-blown war. Hezbollah has denied responsibility for the initial attack but has promised to respond to any Israeli aggression. Both sides have exchanged fire since the October 7 Hamas attack, with Hezbollah's rocket attacks on Israel significantly increasing in frequency and intensity.
