The father of a man who shot dead 49 people in Orlando says the nightclub where the attack took place is partially to blame for not stopping his son's rampage.
Seddique Mateen says his 29-year-old son should have been 'neutralised' sooner.
It's emerged Omar Mateen may have visited the club several times before.
President Obama says the attack is being treated as a terrorist incident and Mateen's dad says it could have been prevented.
