Iran's top nuclear negotiator Saeed Jalili and EU foreign policy chief Javier Solana will hold talks on ending the atomic standoff on July 19 in Geneva, the official IRNA News Agency reported on Friday.

"They are to continue their negotiations about the package on Saturday, July 19," IRNA quoted Ahmad Khadem al-Melleh, spokesman for the secretariat of Iran's supreme national security council, as saying.

World powers last month presented Iran with a package aimed at ending the five-year-old nuclear crisis, notably offering Tehran technological incentives in exchange for suspending the sensitive process of uranium enrichment.

On Wednesday, Solana's spokeswoman refused to confirm a press report from Tehran that he would visit the Iranian capital on July 19.

"In principle, we are expecting a meeting" with Iranian authorities "before the end of the month," Cristina Gallach told AFP. But she added that "neither the date nor the meeting's location" had been set.

Western governments say they fear Iran's nuclear drive is aimed at making atomic weapons, a charge that Tehran vehemently denies. It says its nuclear programme is for purely peaceful ends, to help provide energy when fossil fuels run out.
