TEHRAN, Sept. 23 (Xinhua) -- A top Iranian security official said on Tuesday that Tehran is open to negotiations with the West if it is presented with a "reasonable and fair" nuclear proposal that safeguards its interests, according to the official news agency IRNA. "They chant the slogan of (favoring) negotiation, but pursue other objectives in practice," he said. During the meeting, they reviewed the talks held over the past weeks to find a diplomatic solution to Iran's nuclear issue. The UN Security Council on Friday failed to adopt a resolution that would extend sanctions relief for Iran. The sanctions are expected to take effect later this month if no new actions were taken in the Security Council.
