More than $600,000 (£468,000) has been raised for the families of the three US men attacked while defending a Muslim teenager and her friend on a train.

Taliesin Myrddin Namkai-Meche and Ricky John Best were killed and Micah David-Cole Fletcher was severely injured in Portland, Oregon on Friday.

They all intervened after a man launched into a verbal tirade against the teens, one wearing a hijab.
