At least one person has died and several injured after a shooting and stabbing at a motorcycle show in the US state of Colorado.
Police in Denver said “numerous” people were hurt in the attack at the Denver Coliseum, which happened just before 13:00 local time (20:00 GMT).
The venue was hosting the Colorado Motorcycle Expo, one of the largest events of its kind in the US.
Health officials tweeted that nine people were being treated in hospital.
At a press briefing, Raquel Lopez, a spokeswoman for Denver Police, said there was at least one stabbing as well as shooting.
No-one was in custody, she said.
The Denver Post reported that the incident started as a feud between rival motorcycle gangs.
In May 2014, a shootout between rival bike gangs in Waco, Texas, killed nine people and led to more than 170 arrests.
