Israel's Northern Command chief, Major General Rafi Milo, announced that the military is on heightened alert amid concerns that a potential United States strike on Iran could prompt Iranian retaliation against Israel. Milo emphasized that the situation is unpredictable and that Israel is prepared for any escalation, including possible involvement from Hezbollah. The United States has increased its military presence in the region, with warships moving closer to Iran, while Iranian officials have warned that any attack will be treated as an all-out war. The tense atmosphere has led to airlines canceling or rerouting flights over the Middle East, and Israeli aviation authorities have warned that airspace closures could occur if the situation deteriorates further.
