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.

Up to 26 centimetres of snow fell over northern parts of the South Korean capital, as hundreds of flights were cancelled and homes in multiple areas left without power.

A deadly and historic November snowstorm paralyzed parts of South Korea on Wednesday, as heavy snow warnings led to widespread power outages and flight cancellations.
