WASHINGTON - The Department of Homeland Security is further increasing aviation security in response to intelligence indicating Islamist terrorists were planning another attack on the United States.

The new regulations — which are to be announced later Thursday — were not described in detail, but a senior U.S. official told NBC News on condition of anonymity that they would include further in-flight restrictions in passengers’ movement, more random pre-flight screening of passengers and an increase in the number of federal air marshals on flights.
