Iran must give clear reply or face sanctions: U.S.

WASHINGTON (Reuters) - Iran faces "further measures" such as sanctions if it does not respond positively to an offer by major powers to suspend its nuclear program for incentives, the U.S. State Department said on Monday.

"We agreed in the absence of a clear, positive response from Iran that we have no choice but to pursue further measures against Iran as part of this strategy," said State Department spokesman Gonzalo Gallegos. He added that Tehran said it would provide a written reply to the offer on Tuesday.
