TOKYO (Reuters) - A 72 year-old retired soldier blew himself up in a park in the Japanese city of Utsunomiya, killing himself and injuring three other people in an apparent suicide, state broadcaster NHK reported.

A second explosion, separate from the blast that killed the former Self Defence Force member, caused a fire in a nearby parking lot, while the man's home 8 km (5 miles) from the park burnt to the ground, the report said.
