The United Nations atomic watchdog said Thursday it installed surveillance cameras to monitor a new centrifuge workshop at Iran's underground Natanz site after a request from Tehran, even as diplomatic efforts to restore its tattered nuclear deal appear stalled.
The start of work at the new workshop comes after Iran's centrifuge facility in Karaj found itself targeted in what Iran described as a sabotage attack in June. Natanz itself has twice been targeted in sabotage attacks amid uncertainty over the nuclear deal, assaults that Tehran has blamed on Israel.
