Three young women and a man were killed on Tuesday after the truck carrying 12 members of their pop band collided with another truck travelling in the opposition direction in Kampong Cham province.

According to Lem Sothy, deputy police chief of Chamkar Leu district, Sun Dina, the band’s 27-year-old manager and driver, and singers Srey Yan, 25, and Srey Hin, 28, all died at the site of the crash.

Another female band member, whom police did not name, died later in hospital, he said. The crash left eight others injured.

“They drove carelessly. After examining the crash site, we can conclude that the two parties were driving very fast and the drivers were blinded by [each other’s] headlights,” Sothy said.

The crash occurred in the early hours of Tuesday on National Road 71. The driver of the other truck, which carried no passengers, suffered serious injuries.
