As additional deaths were discovered during the incident, the number of people killed in the highway tunnel between Suncheon-Wanju increased to five. The accidents are also being revealed one after another, which seems to have increased as cars collided with each other, starting with the collision of large vehicles.

Police believe the accident began as clashes between military trucks and trucks carrying armored vehicles.

At the entrance of the Saemae 2 Tunnel CCTV, two cars moved together as if they were in a tunnel.

Since then, passenger cars have either halted quickly or crashed lightly, but large vehicles such as tank lorry have not stopped.

The joint police first investigated the trailer and crash truck driver.

The driver reportedly stated, "The trailer slowed down and applied the engine brakes, the car slipped and got into the front car, after which the steering wheel did not listen."

At the time of the accident, KLC released a video of the tunnel snow removal 30 minutes before the accident, but the police open up all possibilities.

The vehicle was too dangerous and the size of the car was too big for the tunnel.

Two bodies were found in the process, killing five people.

The lanes in Suncheon will resume traffic, but the lanes in Wanju will be opened after the tunnel safety diagnosis and repair.
