The Pentagon is concerned because Safir missiles use the same components as those needed for an intercontinental ballistic missile. But there has been a flurry of activity on an Iranian launchpad that U.S. officials have been watching closely, since the launch of a ballistic missile from the site last week. On Jan. 29, Iran launched a new type of medium-range ballistic missile prompting an emergency meeting of the U.N. Security Council on Jan. 31. Another satellite photo showed an additional Iranian missile launcher and nine vehicles in the desert not far from the launchpad. Resolution 2231 calls upon Iran not to conduct ballistic missile tests -- but does not forbid the nation from doing so.
