Power was cut to about 800,000 households in Tokyo and Saitama Prefecture on Monday afternoon after an Air Self-Defense Force jet severed a power line before it crashed, killing its two crewmen.

The T-33 trainer jet crashed into a field near Kashiwabara Junior High School in Sayama, Saitama Prefecture, at 1:46 p.m. and burst into flames. The two ASDF crewmen aboard -- Lt. Col. Hirofumi Nakagawa, 47, and Maj. Yoshihiro Kadoya, 48 -- died in the crash, police said.

The crash site is about 3.6 km north of the ASDF Iruma base where the trainer jet was stationed, and the jet had entered its final approach when it crashed, they added. The cause of the accident was not immediately known.
