Schools across the U.S. have been rocked by a spate of false threats of violence in recent weeks, forcing them to evacuate or temporarily close. Why it matters: Threats of bombs, shooters and other dangers disrupt learning and stir community-wide anxiety about school safety.

A 10-year-old student has been charged with felony terrorist threat for allegedly threatening to commit a school shooting at a Kerrville, Texas, middle school, police said Monday.

The number of threats of violence against area schools has risen to the dozens as school safety concerns spike nationwide, local and federal law enforcement officials said Friday.
