Thirty-four people were injured when a tourist bus and a Self-Defense Forces truck collided Saturday on a road in Fukuoka Prefecture, police reported.

The truck's two SDF personnel sustained broken bones, while the tour conductor and 31 passengers on the bus received minor injuries in the accident in Asakura, according to the police. The bus driver was unhurt.

The bus and midsize truck collided inside a tunnel around 9 a.m. Saturday when the bus hit the truck while trying to overtake it, causing the SDF vehicle to overturn, the police said.

The tourist bus was carrying passengers on a day trip from Fukuoka to Tsukumi, Oita Prefecture. The two SDF personnel, stationed at the Ground Self-Defense Force base in Kasuga, Fukuoka Prefecture, were en route to training in Oita Prefecture.
