A foreign couple died after they accidentally fell from the rooftop of a three-story building in central Seoul while they were kissing each other, police said Sunday.

The Yongsan Police Station said that at around 2 a.m. on Sunday, a 31-year-old American man and a 26-year-old South African woman dropped from the rooftop of their house in Itaewon.

Police are now trying to ascertain the exact cause of their death. But they believe that chances are little that they were pushed by someone.

Witnesses said the man was pulled to the ground as he was trying to save his girlfriend, who fell over first, adding the couple was kissing before the accident. They died right after they were transported to a nearby hospital.

The couple has rented part of the house and lived there together for some time, investigators said. (Yonhap)
