The U.S. is urging all non-essential personnel to leave the country of Yemen amid "extremely high" terror threats uncovered after a letter between al Qaeda operatives was intercepted, warning of an imminent attack against Americans.

At least one military aircraft has transported around 90 non-essential employees out of the region, and Greg Palkot reported on America's Newsroom this morning that the generally well-secured Embassy is now even more secure. Additional tanks and troops and U.S. surveillance aircraft overhead have been put in place to counteract the surge of threats to the region.

Palkot also shared new ground reports of a U.S. drone strike said to have taken out four al Qaeda militants in the Marib province of Yemen. This marks the sixth such strike this month.
