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.

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.

The worst November snowstorm in half century has hit Seoul, grounding hundreds of lights countrywide and disrupting commuter traffic in the capital.
