As bullets fly, teacher sings

As narcos battled near an elementary school in Monterrey, Mexico, kindergarten teacher Martha Rivera Alanis led her class in a duck-and-cover drill and sing-along.

The Nuevo Leon state government honored Rivera a 33-year-old mother of two, for “outstanding civic courage” for keeping the children from panicking.

Five people were killed in the gun battle at a taxi stand.

The teacher posted the video, made on her cell phone, to her Facebook account. It was reproduced on YouTube and went viral.
