No evidence Islamic State knew of San Bernardino shooters - source
WASHINGTON (Reuters) - Investigators have no evidence Islamic State knew the two alleged shooters in the San Bernardino, California, rampage and no evidence from their home suggests any substantive connection to a foreign terror organisation, a U.S. government source said on Friday. The source said there was nothing to suggest the militant Islamic group "even knew who they were." (Reporting by Mark Hosenball; Writing by Tim Ahmann; Editing by Andrea Ricci)
