WASHINGTON (Reuters) - It appears that no Americans were killed or injured in an attack at a Christmas market in Strasbourg, France, U.S. Secretary of State Mike Pompeo says told Fox News in an interview on Wednesday.

U.S. President Donald Trump, in a separate tweet, cited the “very bad terror attack in France” but gave no other details.
