The Islamic State is operating clandestine terrorist cells in Britain, Germany and Italy, similar to the groups that carried out the attacks in Paris and Brussels, the top-ranking American intelligence official said on Monday.
When asked if the Islamic State was engaging in secret activities in those nations, the official, James R. Clapper Jr., the director of national intelligence, said: “Yes, they do. That is a concern, obviously, of ours and our European allies.” He then added, “We continue to see evidence of plotting on the part of ISIL in the countries you named.” ISIL is another name for the Islamic State.
Mr. Clapper, speaking to reporters at a breakfast meeting organized by The Christian Science Monitor, became one of the most senior Western officials to publicly acknowledge the Islamic State’s extensive reach into Europe, which has set off growing fears among American and European spy services and policy makers. The Islamic State has vowed to conduct attacks in those three European countries.
