A Hungarian woman has been killed and a South Korean woman seriously injured in a collision between two boats during a night-time tourist trip to watch fireflies on a Thai river.
Around 20 other people, mainly from South Korea, were injured in the accident at Amphawa, a popular tourist destination about 35 miles west of Bangkok.
Police lieutenant colonel Bhakin Sivamethakul said one boat, carrying 21 South Koreans and two Hungarians, was returning at the end of the trip when it was struck by an empty boat going in reverse.
The Hungarian tourist was hit on the head in the collision.
The drivers of both boats face a charge of causing death through negligence.
The 61-year-old woman's 62-year-old husband was injured and a 26-year-old Korean woman was in intensive care at a hospital.
The death through negligence charge carries a penalty of up to 10 years’ imprisonment.
