Iran threatens to cancel nuclear deal

Iran on Sunday threatened to cancel the nuclear deal with world powers unless a probe into allegations of its past weapons research is closed, AFP reported.
The declaration, by a top Iranian security official, comes after the head of the UN nuclear watchdog said a report into the possible military dimensions of Iran's activities would not be "black and white."
Iran has always denied seeking to develop an atomic weapons capability, insisting its nuclear program is for peaceful energy production and medical purposes only.
