Tensions in the Middle East have escalated sharply as reports suggest a possible United States military strike on Iran within a day. Britain has started withdrawing its personnel from the United States-run Al Udeid Air Base in Qatar, following similar precautionary actions by American forces. Several European nations, including Italy and Poland, have advised their citizens to leave Iran, and German airline Lufthansa is preparing for potential evacuations and flight disruptions in Israel. Amid these developments, Iran-backed Hezbollah has stated it will not guarantee restraint if Iran is attacked, raising fears of a broader conflict as military and civilian movements intensify across the region.
