A gunman believed to have opened fire at a high school is dead from a self-inflicted gunshot wound, police have said.
Police have not yet released details, but reports suggest as many as seven people where shot at around 10.45am local time (6.45pm, BST) at Marysville-Pilchuck High School in Washington state.
Three of the injured were taken to Providence Regional Medical Center in nearby Everett, including one with a head wound, while police went room to room with guns drawn, marking cleared areas with tape amid fears the gunman was still in the building.
And law enforcement sources told the Seattle Times that the gunman shot himself after opening fire on students, some of whom were evacuated from the building and others told to stay inside their classrooms.
The school is currently on lockdown, the district said in a statement.
