US Embassies across the Mideast and North Africa remain closed Monday, and many will be shut down all week. This is the most severe terror warning since the September 11th attacks. Rhode Island Congress Man Jim Langevin is on the House Intelligence Committee.
Langevin said, "We know that there is something underway in terms of a major terrorist attack. Whether it is one single event or multiple events happening simultaneously, we are unsure."
Langevin says if there is an attack, it's most likely going to be overseas, but intelligence can not rule out an attack on US soil.
The terror warning couldn't come at a worse time. That's because this is a peak travel season for Americans visiting overseas.
As of now, no Americans are being told to cancel their travel plans. They are, however, being warned about being careful if going overseas.
"Well, the best advice is to be very aware of your surroundings. Anything unusual; people acting in an unusual fashion" says Senator Jack Reed.
Luggage is always something to keep an eye on. Items such as backpacks that are left alone should be avoided and then reported. And keep in mind that in most of Europe and Asia, the US Embassies remain open.
Senator Sheldon Whitehouse says, "The sensible advice is to watch the news carefully. And if you feel worried, contact the American embassy locally."
The state department also operates travel websites with up to the minute advice and warnings.
