There’s a belief a shooter in Dallas, Texas, was motivated by violent ideology and divisive rhetoric.
One detainee is dead and two more are critically injured after a rooftop sniper fired indiscriminately at the Immigration and Customs Enforcement Facility, also known as ICE yesterday.
The gunman later died from a self-inflicted gunshot.
Dallas ICE Director Joshua Johnson says it's being investigated as an act of targeted violence.
US Correspondent Richard Arnold told Mike Hosking the shooter reportedly left behind notes including a game plan of the attack and target areas at the facility.
One note reportedly says he wanted to give ICE agents a sense of “terror”, the shooter describing ICE employees as "people showing up to collect a dirty pay check".
