HOLYOKE, Mass. (AP) - Authorities say no one was hurt when a school bus carrying 10 young students was struck by two stray bullets.

The bus carrying students between the ages of 6 and 13 from the Holyoke Community Charter School was struck Wednesday afternoon while bringing them home for the day.

Police do not think the bus was specifically targeted.

Investigators say nine shots were fired.

Mayor Alex Morse called the shooting "appalling." He and Police Chief James Neiswanger (NICE'-wong-er) vowed to bring those responsible to justice.

A witness told investigators he saw a silver car with a Hispanic male in a gray hoodie shoot at the car in front of him. The witness said both cars then left the area.

There have been no arrests.
