SAN BERNARDINO, Calif. (Reuters) - Islamic State said on Saturday that the married couple who killed 14 people in a mass shooting in Southern California were its followers, and FBI agents raided a home apparently belonging to a friend of the husband.
Islamic State's claim came in an online audio broadcast three days after U.S.-born Syed Rizwan Farook, 28, and his Pakistani wife Tashfeen Malik, 29, opened fire with assault rifles on a holiday party for civil servants in San Bernardino, 60 miles (100 km) east of Los Angeles.
