Police in Colorado Springs say a gunman remains holed up inside a planned parenthood building following a shooting.

At least nine people have been transported to local hospitals. Colorado Springs police say four officers were injured in the shooting. At one point, officers exchanged gunfire with the suspect. Police are trying to evacuate people from the building. Police say the area near the city's Centennial Boulevard is not secure, and that people should avoid the area.

Those already in that area are being asked to stay put in nearby stores.
