Iran may face more sanctions

From Reuters

Iran delivered a letter to world powers Tuesday but gave no concrete reply to a demand that it freeze its nuclear activity, a defiant step that the United States has warned could lead to more sanctions.

The letter was in response to a June offer by six nations to forgo seeking more U.N. penalties if Iran froze expansion of its nuclear work. It read, in part, “Iran is ready to provide a ‘clear response’ to your proposal at the earliest possibility, while simultaneously expecting to receive your ‘clear response’ to our questions and ambiguities as well.”

The major powers say they fear Tehran wants to build an atomic bomb. But Iran insists that it only wants nuclear technology to generate electricity.
