U.S. strikes Isfahan as Iran targets fully loaded oil tanker off Dubai

U.S. strikes hit a city on Tuesday (March 31, 2026) that is home to one of Iran’s main nuclear sites, sending a massive fireball into the sky, and Tehran attacked a fully loaded Kuwaiti oil tanker in the Persian Gulf.

The attacks were testament to the intensity of the war more than a month after the United States and Israel launched their first strikes. The conflict has left more than 3,000 dead and caused major disruptions to the world’s supply of oil and natural gas.

Mr. Trump, who has vacillated between insisting there is progress in diplomatic talks with Iran and threatening to widen the war, shared footage of the attack on Isfahan.

The video shared by Mr. Trump appeared to show a massive attack on Isfahan, and NASA fire-tracking satellites suggest explosions happened in a mountainous region on the city’s southern edge. Iran has not confirmed the attack.

An Iranian drone hit a Kuwaiti oil tanker in waters off the United Arab Emirates city of Dubai, sparking a blaze that was later put out, the Dubai Media Office said. Authorities said there was no oil spill.

U.S.-Israeli strikes also killed four persons, wounded 26 and damaged a Shia Muslim mosque and religious site in northwest Iran, Iranian media reported. State television said the building of the Grand Husseiniya, a hall for Shia gatherings and mourning ceremonies, “was damaged following the enemy’s morning attack on the Ferdowsi street” in the city of Zanjan. It added that “parts of the dome and minarets were damaged.”

Iranian media reported that the strikes had also hit some “military sites”, without specifying the locations.
