Americans are, once again, expressing outrage over a mass shooting, this time at the end of a parade Wednesday honoring the 2024 Super Bowl champion Kansas City Chiefs.

One person was killed and at least 21 others were injured in the attack outside Union Station in Kansas City, Mo.

Doctors and administrators at Children's Mercy, one of three Kansas City, Mo.-area hospitals where shooting victims were transported, said at a press conference that they treated 11 children. Nine of those children suffered gunshot wounds. Their ages ranged from 6 to 15.
