An explosion at a restaurant in northern Japan injured 42 people late Sunday, while surrounding buildings collapsed, police said.
Fires broke out following the incident in the northern city of Sapporo, Kyodo news agency said, and images from the scene showed large flames and plumes of smoke rising in the night air.
A police officer for the Hokkaido region told who spoke to news agency AFP said no one was killed from the explosion.
“There are 42 injuries, but no one was killed,” the officer said.
One witness reportedly said he had smelled gas after the explosion while authorities launch an investigation into the cause of the blast.
The building that housed the restaurant was heavily damaged, as were other nearby businesses, including a real estate company.
National broadcaster NHK said it took firefighters several hours to extinguish the flames, but not before several children got burnt in the blast.
Police warned earlier of possible secondary explosions, according to Kyodo.
