Bushehr's governor Fereydun Hasanvand told Iranian television that of those wounded, 750 had "minor injuries" and the rest had been sent to provincial hospitals.
Last month he sent a delegation to Tehran in the latest of a series of talks to negotiate a possible resumption of site visits, but the head of Iran's atomic energy programme Fereydun Abbasi-Davani said visits to Parchin or any other site were "not on the agenda".
