Heavy snow and freezing temperatures wreaked havoc on road and rail links in parts of Britain Tuesday, forcing the closure of two airports and hundreds of schools, officials said. In northwest England, heavy snow blocked roads and triggered accidents in the Cumbria region while Manchester and Liverpool airports were closed. In Scotland, flights were delayed at Aberdeen and Glasgow airports, while train services were disrupted between Glasgow and Edinburgh, and there were delays on trains from Glasgow to London. Hundreds of schools were closed in Scotland and northern England, including some 60 in North Yorkshire, as teachers struggled to get into work and parents kept their children at home. Meanwhile, the Chinese capital was in the grip of its coldest weather in 20 years Tuesday after snowstorms caused chaos, while South Korea sent out an army of civil servants and soldiers to clear clogged roads. Heavy snow has brought more travel chaos to north China, stranding thousands of truckers for two days on a Beijing highway and 1,400 rail passengers in Inner Mongolia, state media said Tuesday. In South Korea, tens of thousands of civil servants and soldiers were mobilized to clear record snowfalls as freezing temperatures left roads and highways icy in many areas. Weathermen said it stopped snowing late Monday in Seoul and nearby areas but the southwest coast received up to 21 centimeters of snow early Tuesday.
