IN THE EARLY hours of July 2nd a building caught fire in the grounds of the nuclear plant at Natanz in central Iran. Officials downplayed it as an accident in an unfinished shed. But photos showed a building with machinery on the roof. Satellite images added more doubt: scattered debris looked consistent with an explosion, not a fire. The cover story was short-lived. A spokesman for Iran's nuclear agency soon admitted it was a factory for centrifuges used to enrich uranium. The damage, he said, could slow work on advanced models. The apparent blast was one in a string of unusual incidents around Iran this summer (see map). On June 26th there was an explosion near Parchin, a military base south-east of Tehran that produces ballistic missiles. It was big enough to light the night sky in the capital. There have also been fires or explosions at power plants, clinics and other facilities. Some have innocuous explanations, like gas leaks.
