Iran will not turn on the UN nuclear watchdog's cameras it removed in June until a 2015 nuclear deal is restored, the head of Iran's Atomic Energy Organization Mohammad Eslami said on Monday, according to Tasnim news agency.

"Those cameras are related to the nuclear deal. If Westerners return to this pact and we are certain they will not commit any mischief, we will make a decision on these cameras," Eslami said.
