US, UK: Iran must give clear reply or face sanctions

       Iran faces more punitive measures, including sanctions, if it does not respond positively to an offer by major powers to rein in its nuclear program in exchange for incentives, the US 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," department spokesman Gonzalo Gallegos told reporters. UK joins call, demands 'unambiguous and positive' reply Major powers - the United States, Russia, China, France, Britain and Germany - laid down an informal deadline to Iran of two weeks, which expired over the weekend, to respond to an offer of trade and technical incentives to halt enrichment, media reported. "Iran has a clear choice of engagement or isolation," Gallegos added. (20,59)
