Iran and six world powers – the USA, Russia, China, the UK, France and Germany – are set to hold talks on Tehran's disputed nuclear program in Geneva on January 18, the European Union said on Wednesday, according to Reuters.

"The meeting will be at political directors' level, chaired by EU Political Director Helga Schmid,” an EU statement said.

The November 24 deadline saw no conclusion to the prolonged talks, so the parties decided to carry on negotiations till the end of June.
