California shooters had been radicalised 'for some time'
California shooters Syed Farook and Tashfeen Malik had been radicalised "for quite some time" before killing 14 people in San Bernadino last week, the FBI has revealed.
Both took part in target practice, on one occasion just days before the deadly attack on an office Christmas party.
Syed Rizwan Farook, 28, and Tashfeen Malik, 27, killed 14 people and injured 21 others in the attack on an office Christmas party in the city of San Bernadino. Many of the victims were food inspector Farook's colleagues.
