French hostage crisis: US warns Americans of global terror threat

WASHINGTON (AFP) - The United States on Friday warned Americans to beware of "terrorist actions and violence" all over the world, following the attacks on the Charlie Hebdo magazine and a Jewish supermarket in Paris.

"Recent terrorist attacks, whether by those affiliated with terrorist entities, copycats, or individual perpetrators, serve as a reminder that US citizens need to maintain a high level of vigilance and take appropriate steps to increase their security awareness," the State Department said.
