Two small explosions outside U.S. military base in Japan

Nov. 29 (UPI)-- Two small explosions were heard by residents outside the Yokota Air Base near Toyko late yesterday evening.

The Tachikawa Police Department received reports from residents who heard "two small, cannon-type bangs" around 11 p.m.

Investigators discovered an "improvised launch device" comprised of two metal pipes, lead wire, and a battery in an empty lot near the base. Yokota spokesman Captain Ray Geoffroy reported no injuries or damage. No projectiles have been located, and no one has claimed responsibility.
