Intel warning

Intelligence officials: ISIL determined to strike U.S. this year

The Islamic State militant group will "almost certainly" remain a threat to the U.S. homeland and seek to launch or inspire attacks on American soil in 2016, a top U.S. intelligence official warned Tuesday.

Attacks in the United States by the group, also known as ISIL, "will probably continue to involve those who draw inspiration from the group's highly sophisticated media without direct guidance from ISIL leadership," James Clapper, director of national intelligence, testified in a rare public hearing on Capitol Hill about intelligence threats facing the nation.
