Heavy Strike Wave Hits Tehran in Early Hours of Day 36

Residents report widespread explosions and fires across the capital as US-Israeli campaign continues overnight into Saturday

In the early hours of Saturday, April 4 — Day 36 of the US-Israeli air campaign — residents of Tehran reported heavy explosions and large fires visible across the city, including in the northern districts near the Alborz Mountains. The strike wave continued the sustained pressure on Iranian regime and military infrastructure that has defined the campaign's fifth week. The overnight targeting pattern, consistent with prior waves, reflects a deliberate operational tempo: keeping Iranian air defenses stressed around the clock while striking assets that would otherwise disperse or harden. No casualty figures had been released by either side as of early Saturday morning.
