Iran preparing to start plant needed for interim nuclear deal-sources

VIENNA (Reuters) - Iran has taken preparatory action to start up a uranium conversion plant it needs to fulfil an interim nuclear agreement reached with six world powers last year before the accord expires this month, diplomatic sources said.

The launch of the facility would show Tehran's commitment to the landmark Nov. 24 deal as it holds talks with the United States, Russia, France, Germany, Britain and China on a long-term settlement of the dispute over its atomic aims.
