Details are still coming in, but sadly there has been another school shooting in the U.S. today (May 18), as it's been reported by CNN that 10 people were killed by a student at Santa Fe high school in Santa Fe, Texas.

Santa Fe Police Chief Jeff Powell said, "There have been explosive devices found inside the high school, and in the surrounding areas adjacent to the high school."

A male suspect, believed to be a student, has been arrested in the shooting, and a second person -- also believed to be a student -- has been detained as well, Harris County Sheriff Ed Gonzalez said. In addition to those who have passed, CNN reports that at least 12 people are also being treated at three area hospitals.

This marks the third school shooting in the U.S. in the last eight days and the 22nd overall this year. As expected, the news has started to evoke some emotional responses.
