Iran reports 'incident' near Natanz nuclear site

An “incident” has damaged an under-construction building near Iran's Natanz nuclear site, but there was no damage to its centrifuge facility, a spokesman for Iran's Atomic Energy Organization said Thursday.

Behrouz Kamalvandi made the comment in a report published by the state-run IRNA news agency.

Kamalvandi called the affected building an “industrial shed", without elaborating.

There hasn't been any previously announced construction work at Natanz, a uranium enrichment centre some 250 kilometers (155 miles) south of the capital, Tehran.

Natanz includes underground facilities buried under some 7.6 meters (25 feet) of concrete, which offer protection from airstrikes.

It is among the sites now monitored by the International Atomic Energy Agency (IAEA) after Iran's nuclear deal with world powers.

The IAEA did not immediately respond to a request for comment over the incident.
