A shooting at a family planning clinic in Colorado Springs has left two civilians and a police officer dead, with the suspected gunman under arrest.

Nine other people were injured during the standoff at the Planned Parenthood clinic, which lasted five hours before the suspect surrendered.

A number of people were trapped inside the building as shots were exchanged.

The motive remains unclear. The Planned Parenthood group has drawn anti-abortion protests in the past.

A law enforcement source identified the suspect as Robert Lewis Dear, from North Carolina. No other details were provided.
