VIENNA (Reuters) - Six world powers and Iran started a second day of talks in Vienna on Wednesday on Tehran's contested nuclear programme, seeking to close a vast gap in expectations about what a final agreement should look like.

The meeting, which began on Tuesday, aims to set out a broad agenda for talks that could in time produce an agreement on the permissible scope of Iran's nuclear activities and lay to rest Western concerns about their possible military dimension.
