Syed Farook had contact with Al Qaeda-affiliated Nusra Front in Syria and al-Shabab in Somalia.
I'm guessing the motive is still 'unclear'
San Bernardino shooter Syed Rizwan Farook had contact with people from at least two terrorist organizations overseas, including the al-Qaida-affiliated Nusra Front in Syria, a federal law enforcement official said Friday.
His wife and fellow shooter, Tashfeen Malik, also pledged allegiance to an Islamic State leader in a Facebook posting, two federal law enforcement officials said. The revelations came as the FBI formally announced it was investigating the shooting rampage as an act of terrorism.
FBI Director James Comey said the assailants showed signs of "radicalization" but that there was no evidence they were part of a larger terrorist network.
As the investigation expands, the law enforcement source said, agents are trying to learn more about the couple's contacts in the U.S. and overseas, especially those in Pakistan
One key question, said the official, "is if they had any weapons or terror training in Pakistan." The source described "some kind" of contact between Farook and people from the Nusra Front and the radical al-Shabab group in Somalia. It's unclear what type of contact or with whom.
Authorities in Pakistan also said Friday that they were investigating whether Malik had ties to Islamic militant organizations.
