Seized nuclear material in Iraq "low grade" - U.N. agency

VIENNA (Reuters) - The U.N. atomic agency said on Thursday it believed nuclear material which Iraq said had fallen into the hands of insurgents was "low grade" and did not pose a significant security risk.

Iraq told the United Nations that the material was used for scientific research at a university in the northern town of Mosul and appealed for help to "stave off the threat of their use by terrorists in Iraq or abroad".
