WJBK - A rare worldwide travel alert warning Americans about new threats posed by extremists and copycat bombers.
The warning comes just as millions prepare to travel for the Thanksgiving holiday, just a few weeks since the Paris attacks.
Ose Parlee just learned about the worldwide travel alert just issued by the state department that is cautioning Americans about the possible risks, especially as we approach the holidays.
"Oh wow, that worries me actually," said Parlee.
New information suggests ISIS, Al-Qaida, Boko Haram and other terrorist groups could strike again.
"I know there has been a lot of stuff going on with Paris, Beirut, so I'm hoping they don't target the US again," said Parlee.
The US is learning of the latest threats of international terrorism by exchanging information with its allies. As we approach the busiest travel day of the year, some are on edge.
"It's a little worrisome, understanding what else has been going on in the world. There's nothing preventing me from flying," said Edan Evenhaim, who is traveling over the holidays.
"It is scary, but I can't live my life in fear. We have to get where we need to go, see family for the holidays," said Lindsay Boujoulian, who won't stop traveling. "It's unfortunate, but it won't change the way I travel."
It won't change plans for people like Thomas Coe, but the government wants people to be more aware of their surroundings, pointing to the recent attacks where extremists have targeted sporting events, theaters, open makers and airlines.
The state department is telling US citizens to exercise vigilance when in public places, using transportation, in crowded places or at large events.
"We should be vigilant. If you see suspicious stuff going on, I don't need the government telling me say something, I should check something on it or call someone," said Coe.
The alert lasts until February 24.
