Islamists Strike Southern California:

WASHINGTON — The woman who helped carry out the shooting in San Bernardino, Calif., on Wednesday had pledged allegiance to the Islamic State in a Facebook posting, according to federal law enforcement officials.

There is no evidence the Islamic State directed the woman, Tashfeen Malik, and her husband Syed Rizwan Farook, to launch the attacks, which killed 14 and wounded 21, the officials said. But the Facebook post has led investigators to believe that the couple took inspiration from the group, they said.

“At this point we believe they were more self-radicalized and inspired by the group than actually told to do the shooting,” one of the officials said. The officials spoke on the condition of anonymity because the investigation is continuing.
