Two people were killed when their car crashed into the sea in South Korea's southeastern area, police said Sunday.

A Kia Motors' Morning subcompact drove into the sea from a sandy beach around 9 p.m. Saturday with a thunderous noise, the police said.

Emergency crew members found the vehicle overturned about 30 minutes later and pulled a man and a woman out of the car before rushing them to a nearby hospital, where they were pronounced dead, the police said.

The police identified the 43-year-old man by his family name Kwon and the 43-year-old woman by her surname Yang. Both lived in Pohang, an industrial town on South Korea's southeast coast.

The police recovered the vehicle around 11:20 p.m. and said an investigation is under way to find the exact cause of the accident. (Yonhap)
