South Korea grappled with heavy snowfall for a second day on Thursday, with dozens of flights cancelled, ferry operations suspended and at least four people reported dead in a bitter winter, though conditions showed signs of easing.

Axar.az reports that, citing Reuters, the winter snowfall was the third-heaviest in Seoul, the capital, since records began in 1907.

More than 40 cm (16 inches) of snow piled up in parts of Seoul by 8 a.m.,one person died and two were injured at a golf range after a net overladen with snow collapsed late on Wednesday, while another was killed in the similar collapse of a protective tent at a car park.

Traffic accidents on highways east of the capital killed at least two more, reports showed.

Seoul’s main airport, Incheon, was the worst affected, with passengers facing delays of two hours on average, while 14% of flights were delayed and 15% cancelled on Thursday.
