Several people are in critical condition, after a mass-shooting in a US gay night club.

Five people are dead, and another 18 injured, after a gunman opened fire at Club Q in Colorado Springs.

The suspect -22-year-old Anderson Lee Aldrich- is being treated for injuries while in custody.

US correspondent, Richard Arnold says it echoes 2016's Orlando gay night club shooting massacre.

He says it appears an AR-15 semi-automatic weapon was used as well as another weapon, with the gunman wearing a bullet-proof vest.
