The Isfahan “oops” was a fairly serious industrial “accident”. Go to the link below and check out the before and after satellite photos of Iran’s former baby formula, missile/uranium enrichment/ nuclear plant.
The photos are at the end of the report. Be sure to click the after view.
From the report: “Iranian officials denied that the city had been hit by an explosion or said that the blast was at a petrol station or even from a butt that fell into a porta-potty igniting accumulated methane gas. Mohammad-Mahdi Esma’ili, Isfahan’s deputy governor in political and security affairs, called the reports of an explosion “sheer lies,” according to the IRNA news agency. An official from the city’s fire department also denied that there had been an explosion, although they said that a large cat which had fallen from a tall tree may have caused the tremors felt throughout the city, whose nuclear facility processes uranium to be fed to the Natanz fuel enrichment facility. Or at least it did before the recent explosion.”
