GANGNEUNG, South Korea, Dec. 18 (Yonhap) -- Three senior high school students were found dead and seven others unconscious at a pension in the northeastern province of Gangwon, possibly due to carbon monoxide poisoning caused by inadequate ventilation, local police and firefighters said Tuesday.

The owner of the pension, located in the city of Gangneung on South Korea's east coast, found the 10 people around 1:12 p.m. Police said the students were vomiting and foaming at the mouth.

The living room and other rooms at the pension where they were staying contained high concentrations of carbon monoxide, police said.

According to firefighters, levels of carbon monoxide concentration were detected at 155 parts per million (ppm) at the scene, well above the standard 20 ppm.

Police said they found the gas boiler at the pension disconnected from the ventilation pipe, leading them to believe that poor ventilation might have caused the incident.

Police said they'll continue to explore all kinds of possibilities. And Lee Jin-ho, head of the Gangneung Fire Station, told reporters, "We are treating this as an accident, not a suicide or a murder."

The students, all of whom are males who attend Daeseong High School in Seoul, were on an excursion after finishing the state-administrated scholastic aptitude test for university entrance.

Of the seven injured, five are being treated at Gangneung Asan Hospital in Gangneung. The other two, said to be in critical condition, were transferred to Wonju Severance Christian Hospital in Wonju, about 120 kilometers west of Gangneung, for hyperbaric oxygen treatment.

A doctor at Gangneung Asan said the conditions of the five patients there have improved slightly, though it was too early to tell when they would regain consciousness.

According to police, the students stayed at a two-story unit. Two were found in the bedroom on the first floor, four in the living room on the first floor and four others on the upper floor. The owner of the pension told police that he heard some students moving as late as 3 a.m. Tuesday.

They made reservations at the holiday property with their parents' consent and arrived at the pension around 4:00 p.m. the previous day. The high school had reported the group's trip to Gangneung to the Seoul Metropolitan Office of Education.
