The president's social media message came after U.S. strikes hit a city 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.
Trump warned this week that if a ceasefire is not reached “shortly,” and if the Strait of Hormuz is not reopened, the U.S. would broaden its offensive, including by attacking the Kharg Island oil export hub and possibly desalination plants.
Israel and the U.S. launched a wave of strikes on Iran, hitting Tehran in the early morning. Israel also said it had launched a new wave of strikes targeting what it described as Hezbollah infrastructure in Beirut.
The video shared by 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.
A satellite image taken just before the June war suggests Tehran transferred a truckload of highly enriched uranium to a nuclear facility about 20 kilometers (12 miles) from Tuesday's strikes.
Analysts believe the truck — which the image showed going into a tunnel loaded with 18 blue containers — likely carried most or all of Iran’s stockpile of uranium enriched up to 60% purity. That’s a short, technical step from weapons-grade levels.
