Oklahoma City, Ok. – Oklahoma's move to change its terrorism alert level followed the federal government's lead today in lowering the national alert level by one from orange or high, where it had been for about three weeks, to the middle yellow level. The yellow elevated condition is declared when there is a significant risk of terror attacks, when neither a specific region nor target in the U.S. has been identified by intellegence information presented at the federal level. According to U.S. Attorney General John Ashcroft and Homeland Security Secretary Tom Ridge, one factor in the reduction decision was the end of the Muslim holiday period of hajj. The action was accompanied by their caution that citizens and law enforcement officials should not reduce vigilance. They indicated some of the extra protection mechanisms may be altered. Oklahomans can receive email alerts about chances in the terror advisory system through the state Office of Homeland Security.
