Tensions in the Middle East surged after Iran shut the airspace around Tehran’s Imam Khomeini International Airport following fresh Israeli airstrikes. Explosions were reported in Tehran, Isfahan and Tabriz as Israel said it targeted military sites in central and western Iran. The dramatic escalation comes despite U.S. efforts to prevent a wider conflict, raising fears of another dangerous spiral in the region. Oil markets and global security watchers are now closely monitoring the rapidly evolving situation.
