As authorities collect more information on the shooting at San Bernardino which left 14 people dead, it appears that it is now being investigated as a terror attack.
The gunmen, Tashfeen Malik, 27, and her husband Syed Rizwan Farook, 28, have now been said to have had links with the Islamic State.
The FBI has claimed that Malik had pledged allegiance to the Islamic State leader, Al-Baghdati in a Facebook post a few months ago.
The attack by the couple took place at a social service center where San Bernardino county workers were having a party.
