KNOXVILLE: Police say one person is dead and and officer was injured Monday at a high school in the east Tennessee city of Knoxville, authorities said, adding that the scene had been secured.

The Knoxville Police Department tweeted that authorities were at the site of the shooting at Austin-East Magnet High School. The online posting said a Knoxville Police Department officer was reported among the victims.

Police urged people to avoid the area, adding a reunification site had been set up on a baseball field behind the school for students to be reunited with family.

Last week, Republican Gov. Bill Lee signed off on legislation that would make Tennessee the latest state to soon allow most adults 21 and older to carry handguns – openly or concealed -- without first clearing a background check and training.

Lee backed the legislation over objections from law enforcement groups, who argued that the state's existing permit system provided an important safeguard for knowing who should or shouldn't be carrying a gun.

The law, which does not apply to long guns, will take effect July 1.
