A gunman opened fire at a community college in southwest Oregon on Oct 1, killing nine people and wounding seven others before police shot him to death.

The massacre is the latest in a series of mass shootings at US college campuses, movie theaters, military bases and churches in recent years. The killings have fueled demands for more gun control in the United States, where ownership of firearms is protected by the Second Amendment of the US Constitution, and better care for the mentally ill.
