At least one gunman opened fire during morning services at a Sikh temple in Oak Creek, Wisconsin, and remained on the loose inside the temple, possibly holding hostages, according to witnesses.
Police, ambulances and the fire department were on the scene at the temple.
The dispatcher for Oak Creek Fire Department said first reports of the shooting came in about 10:30am local time.
Two witnesses said the shooter or shooters were still inside the building.
Helen Collins had never sat behind the controls of a plane and was running out of fuel but she still managed to bring the plane down safely.
