A man wielding a knife killed at least two people and injured 16 others on Tuesday when he attacked a group of schoolgirls close to a bus stop in a city near Tokyo, officials said. Japanese media reported the suspect, who was in his 50s, shouted “I will kill you” as he slashed his victims. He stabbed himself to death after the attack and was pronounced dead at a hospital. Most of the victims were students from a nearby Catholic elementary school who were waiting at a bus stop in the city of Kawasaki.

Three students leapt up from their desks and disarmed a gunman during the shooting at STEM School Highlands Ranch in Colorado on Tuesday. Kendrick Castillo, 18, who led the charge, was shot and killed. Castillo, along with classmates Brendan Bialy and Joshua Jones, minimized the bloodshed from the attack that wounded eight students, authorities said. Jones was shot twice but survived, according to a statement from his family. “Kendrick went out as a hero,” Bialy said. “He was a foot away from the shooter and instead of running the opposite direction he ran toward it.”
