The fog prevented drivers from seeing much more than 10 meters ahead. “I saw the brake lights of the car in front of me turn on and I stopped abruptly,” said to the media one of them, Mr. Lee Gyeong-hoon. The pile-up appeared to have been started when a limousine ran into the back of a car, an Incheon police station spokesman said. 18 departure flights and seven arrival flights were canceled. Rescue workers searched for survivors in damaged vehicles.
