GENEVA -- Iran appeared Thursday to be stiffening its demands in international negotiations aimed at curbing its
, even as other signs suggested that the seven countries at the bargaining table might be close to a deal.
Abbas Araqchi, Iran's deputy foreign minister, said the Tehran regime demanded that world powers begin easing oil and banking sanctions quickly as part of the preliminary deal that has been under discussion for the past five weeks.

The signals coming from Iran have been mixed. While Zarif has urged the world to act on a “historic” opportunity to make a deal, Iran’s supreme leader,
