 U.S. military bases in Europe on high alert this morning. Brian Schmelz has more on that. A U.S. defense official tells Fox News the bases are on high alert for a possible terrorist attack. The official says the warning comes from credible intel that points to an attack within, quote, the next week or so, but it's not clear what the nature of the threat is. Bases are now under the alert level of Force Protection Charlie, meaning the Pentagon has received credible intelligence that some type of terrorist attack is being planned.
