US-Israel Strikes Against Iran

Date: February 28, 2026 • Location: Jerusalem, Israel

This milestone marked the outbreak and beginning of this historic period, which spanned 2026.

The United States and Israel launched strikes against Iran, killing Supreme Leader Ali Khamenei and other senior officials.

Since 28 February 2026, the United States and Israel have been at war with Iran and its regional allies. The war follows the Twelve-Day War in June 2025 and sporadic fighting during the Middle Eastern crisis sparked by the Gaza war, which began in 2023. Amid ongoing US–Iran negotiations regarding Iran's nuclear program, the war began when the US and Israel conducted hundreds of air strikes on targets across Iran, including strikes that assassinated Supreme Leader Ali Khamenei alongside several other Iranian officials.
