A teacher and a student were killed and six others have been hurt during a shooting at Abundant Life Christian School in Madison, Wisconsin, police said.

Victims' injuries range from minor to life-threatening, police said.
Officers responded to the active shooter report around 10:57 a.m. No officers fired their weapons, Madison police said.
"I never saw so many police cars in my life -- just blue and red lights lining the school, lining the streets. Fire department, paramedics, everyone was there," swarming the usually quiet neighborhood, John Diaz de Leon told ABC News Live.
He said he saw officers with long guns at the scene and older students run from the school across the parking lot.
"Later on, very slowly in a more orderly fashion, the younger students holding hands were let out to go across the parking lot," he said.
Officials are working to reunite students with their parents. About 390 students from kindergarten through 12th grade attend the school.

We will not rest until we find solutions that make our schools safe."
"The time for change is long past," Underly said.
