Two men have died in the US trying to stop a man abusing two women of Muslim appearance, Oregon police say.
The abusive man turned on the two men and fatally stabbed them in the city of Portland, police said.
The incident happened on a commuter train. Another passenger was wounded before the attacker was arrested.
The Council on American-Islamic Relations urged President Trump to speak out against increasing Islamophobia in the US.
It accused the president of exacerbating the trend with his statements and policies.
The attack took place at about 16:30 local time (00:30 GMT) on a train at Hollywood Transit Station, police said in a statement. One of the victims died at the scene, the other died in hospital.
Police have identified the suspect as Jeremy Joseph Christian, 35. He has been charged with offences including aggravated murder, attempted murder, intimidation and being a felon in possession of a restricted weapon.
“Suspect was on the train and he was yelling and ranting and raving a lot of different things, including what would be characterised as hate speech or biased language,” said Sgt Pete Simpson.
