A teenager in suburban Dallas has been indicted on a murder charge after allegedly fatally stabbing a fellow student at a high school track meet, prosecutors said. The incident, which occurred on April 2, has deeply affected the local community.

A 19-year-old former student attacked an elementary school in Zagreb, fatally stabbing a 7-year-old girl and wounding three other children and a teacher. The tragic incident has shaken Croatia, where such attacks are exceedingly rare.
