Exclusive-US commander warns troops their videos help Iran, sources say

By Phil Stewart July 29 (Reuters) - The top U.S. commander for the Middle East has warned troops that cellphone videos shared online can help Iran target American bases, and sources told Reuters some deployed personnel could soon be ordered to surrender their phones. Any crackdown on mobile communications would add a new dimension to the conflict for the thousands of U.S. troops in the region, many of whom still rely on phones to periodically message loved ones and assure them they are well.
