Malaysian authorities say a military helicopter crashed into a school in a rural area on Borneo island, injuring at least 22 people including students. The Malaysian air force says the helicopter, which was on a routine training flight, made an emergency crash landing early Tuesday two hours after it took off at a high school in Tawau in Sabah state. It says all 14 people on board the plane survived, and that it will investigate the cause of the crash. District police officer Mohamad Effendi says the helicopter hit part of the roof of the school canteen when it crashed. He said Tuesday the pilot was in critical condition, and that seven students and a school worker also suffered light injuries.
