San Bernardino attackers 'radicalised for some time and had target practice'

The San Bernardino killers had been radicalised “for quite some time” and had taken target practice at gun ranges, in one instance just days before the attack, the FBI said.

In a chilling twist, authorities also disclosed that a year before the rampage, Syed Farook’s co-workers at the county health department underwent “active shooter” training in the same conference room where he and his wife opened fire on them last week.
