Iran urged the United States and its European allies on Sunday to be patient for its response to a package of incentives aimed at persuading Teheran to suspend uranium enrichment. "The package contains legal, political and economic dimensions. All its dimensions have to be studied," Foreign Ministry spokesman Hamid Reza Asefi told reporters Sunday. "We recommend to Europeans that accuracy should not be sacrificed for the sake of speed," he said. Asefi said the package was a serious matter requiring careful study before Teheran came up with a formal response. "The reason that there can't be a speedy response is that we have to hold serious discussions on the contents," Asefi told a press conference.
