Iran Opens Day 21 with Gulf-Wide Missile Campaign; IDF Strikes Tehran and Northern Iran

In the early hours of Day 21 (Friday, March 20), Iran launched a new coordinated missile and drone wave targeting four Gulf states simultaneously — the UAE, Kuwait, Bahrain, and Saudi Arabia — while simultaneously firing ballistic missiles at Jerusalem and northern Israel. All four Gulf air defence systems activated, with UAE and Kuwait issuing official interception statements and Bahrain activating air raid sirens. Saudi Arabia confirmed intercepting a drone in its eastern region. Israel responded swiftly: the IDF announced a new wave of airstrikes targeting 'infrastructure of the Iranian terror regime across Tehran,' continuing the sustained air campaign that IDF Chief of Staff Zamir described as 'not even halfway' complete. The action-reaction exchange on Day 21's opening hours underscores the war's grinding momentum — neither side showing restraint despite massive cumulative damage on both fronts.
