MUNICH (Reuters) - World powers have proposed holding a new round of talks with Iran over Tehran's nuclear work in the week of February 25 in Kazakhstan, a spokesman for EU foreign policy chief Catherine Ashton said on Sunday.

However, Ashton's team, which coordinates diplomatic contacts with Iran on its nuclear program on behalf of the United States, Russia, China, France, Germany and Britain, is still hoping for confirmation of the date and venue from Iran's negotiating team, the spokesman said.
