A cold snap sweeping across East Asia has led to more than 50 deaths in Taiwan and stranded about 90,0000 tourists in South Korea, reported the BBC.

Some 86,000 people were stranded on the South Korean resort island of Jeju on Monday after the biggest snowfall in three decades shut the airport for the third straight day.

Known as the Hawaii of South Korea for its beaches and usually warm climate, Jeju took the brunt of a week-long cold snap that sent the mercury plunging to record lows across the country.

The popular holiday destination has recorded its heaviest snowfall in three decades since Saturday, as the temperature dropped to -6.1 degrees Celsius (21 Fahrenheit).

The transport ministry said Jeju International Airport would remain closed until at least 8:00 pm (1100 GMT) Monday, due to heavy snow and strong winds.

Close to 1,100 flights were cancelled over the weekend and Monday, stranding some 86,000 frustrated travellers on the island, a ministry official said.

Thousands were forced to spend the night at the airport, bundled up in blankets and sleeping on cardboard boxes to avoid the freezing floors.

Although it was spared any snowfall, the capital Seoul recorded its coldest day in 15 years on Sunday, when the temperature fell to minus 18 degrees Celsius.

On Saturday, the state weather agency issued a cold wave warning for Seoul for the first time in five years.
