MONTERREY, Mexico -- The government has honored a kindergarten teacher in northern Mexico who became an Internet hit after a video showed her calmly leading children through a duck-and-cover drill as gunfire rattled outside their school.

The government of the northern state of Nuevo Leon presented teacher Martha Rivera Alanis with a framed certificate for displaying "outstanding civic courage" during Friday's gunfight.

A video on the YouTube website shows Rivera coaxing the 15 children to lie flat on the floor, and leading them in a song popularized by the children's show "Barney & Friends" as hails of gunfire ring out.

Paramedics said gunmen killed five people at a taxi stand near the school Friday.
