On Monday, three children and three adults are dead after a shooting at a private school in the US city of Nashville.
Police reported the shooter was also killed.
Nashville Metropolitan Police spokesman Don Aaron said the 28-year-old woman was armed with at least two semi-automatic rifles and a handgun, and she was shot by police.
Aaron added that in addition to the dead man, no one else was shot.
Authorities were working to determine the shooter's identity and whether it was connected to the school.
About 200 students, from preschool through sixth grade, attend Covenant School.
Hospital spokesman John Howser announced in a statement that three students died after arriving at Monroe Carrell Jr. Children's Hospital in Vanderbilt with gunshot wounds.
Police said the shooting also killed three adult employees.
"In a tragic morning, Nashville joined the dreaded, long list of communities to experience a school shooting," Nashville Mayor John Cooper wrote on Twitter.
There have been 89 school shootings in the United State so far in 2023, according to the K-12 School Shooting Database.
They classify a school shooting as any time a gun is fired on school property.
And last year saw 303 such incidents, the highest percentage in the database of any year, dating back to 1970.
