Iran digs in heels on nuclear centrifuges at Vienna talks - envoys

VIENNA (Reuters) - Iran is refusing to significantly cut the number of centrifuges it intends to keep to produce nuclear fuel, making it hard to imagine a compromise at this week's talks with six powers, Western and Iranian officials said on Wednesday.

The remarks from diplomats close to the talks, who spoke on condition of anonymity, came after the initial rounds of meetings in the Austrian capital between Iran and the United States, Britain, France, China, Russia plus Germany.
