9 killed in collapsed tunnel in Japan
The tragedy occurred in Yamanashi prefecture on Sunday morning. Three cars including a truck and a minibus are buried under the debris.
Three people were reported killed at first. The number of victims has increased now.
Specialists think that loose bolts could be the reason for the collapse of the concrete slabs. The fact that a section of the concrete ceiling of the 4-km tunnel collapsed makes the rescue operation very difficult.
