Iran said Wednesday that a new road map will be prepared next week in Istanbul for ongoing nuclear talks between it and a group of leading world powers, the official news agency IRNA reported.

"Experts from both sides will meet (on Tuesday) in Istanbul for discussing and preparing a new road map for the nuclear talks" IRNA quoted Foreign Minister Ali-Akbar Salehi as saying.

The last round of nuclear negotiations between Iran and the so-called 5+1 group - Britain, China, France, Germany, Russia and the United States - were convened last week in Moscow, but again ended without any results.

"There are some legal and technical issues on the agenda and I am optimistic, although we must be patient, as it might take some time," Salehi said during a visit to Kazakhstan.

All nuclear negotiations in recent years between Iran and the 5+1 group have failed to make headway. Neither side has given any indication since Moscow that there might be the prospect for further talks. (© Copyright 2012 Ha´aretz 06/28/12)
