Obama Extends U.S. National Emergency With Iran

WASHINGTON -- U.S. President Barack Obama has extended the U.S national emergency with respect to Iran, declared on March 15, 1995, by one more year.

Obama said in a notice that "because the actions of the government of Iran continue to pose an unusual and extraordinary threat to the national security, foreign policy, and economy of the United States," the national emergency must continue in effect beyond March 15, 2012.

The United States and Iran have been at odds over a number of issues, including Iran’s sensitive nuclear work and its alleged support for terrorist groups.

Washington broke ties with Tehran following the 1979 Islamic Revolution and the hostage-taking of U.S. diplomats.
