Two apparent explosions have hit the Japanese city of Utsunomiya, killing one person and injuring three others.
The back-to-back blasts occurred before noon at a public park and a nearby car park, according to Japanese media reports.
It is not clear if they are related, and police are investigating the incidents.
A burned body was found in the park after police received a call saying a person was engulfed in flames following what sounded like an explosion, Kyodo News agency said. Three other people were injured.
A few minutes earlier, a car caught fire in the car park. Flames and black smoke shot into the air and repeated bangs could be heard on video posted on the Asahi newspaper's website.
Nearby cars were damaged but no one was hurt.
Utsunomiya, the capital of Tochigi prefecture, is a city of some 500,000 people about 60 miles north of Tokyo. It is near the popular tourist destination of Nikko.
