Israeli Prime Minister Benjamin Netanyahu vowed to push deeper into Lebanon after his military took over the medieval castle of Beaufort on Sunday, calling it a "dramatic shift" in the campaign against Hezbollah. The Iran-backed militant group said on Sunday it targeted Israeli army positions and infrastructure in Shlomi and Nahariya in northern Israel, while air raid sirens blared in the Acre area. Lebanon was dragged into the Middle East war on March 2 when Hezbollah fired rockets towards Israel in retaliation for the US-Israeli killing of Iran's supreme leader.
