THE brother of Florida shooter Nikolas Cruz has been committed to a psychiatric facility, as the family who took the murderer in says ‘we had this monster living under our roof and didn’t know’.

The Islamic State group on Monday claimed responsibility for the shooting, saying in a radio bulletin that it was carried out by "one of the soldiers of the caliphate".

Similarly, Clinton, in a statement, called the attack an "act of terror" but did not speculate about the ideology of the gunman.
