A second migrant has died following a shooting at an ICE facility in Texas.

A sniper shot three people at the Immigration and Customs Enforcement field centre in Dallas last week, killing one straight away and injuring two others.

The gunman, named as 29-year-old Joshua Jahn by US media, died at the scene from a self-inflicted gunshot wound.

In a statement, the family of Miguel Ángel García-Hernández, 32, said he had died from his injuries after being removed from life support. The Mexican national was one of three detainees shot in the attack on Sept 24.
