Incident at US air base in UK involved foreign state, Rubio says

Secretary of State Marco Rubio said Monday that the alleged thwarted attack on a U.S. air base in the United Kingdom "clearly" involved a foreign state. Speaking on Fox News's "Hannity," Rubio called the Sunday arrests of five men suspected of planning an attack on RAF Fairford base "very serious." The incident underscores heightened security concerns at U.S. facilities abroad.
