Iran is vowing to continue with its nuclear program, despite a new report from the U.N.'s atomic watchdog suggesting military-related activities. Tensions escalated this week after the U.N. International Atomic Energy Agency cited what it calls “possible military dimensions” to Iran's nuclear activities. On Wednesday, Iranian President Mahmoud Ahmadinejad said Iran would not retreat “an iota” from its nuclear program, including the enrichment of uranium. In Washington, State Department spokesperson Mark Toner said the United States is considering a new push for sanctions.

Mark Toner: “These are very serious allegations, serious charges, and it’s incumbent on Iran to at last engage with the IAEA in a credible and transparent manner to address these concerns. And I don’t want to rule anything out, but I don’t want to rule anything in. We’re looking at ways that we can apply pressure. We’re always doing that.”
