Heavy snow disrupts UK travel; three boys die after falling into lake

Heavy snowfall blanketed parts of Britain on Monday, disrupting airports, train networks and roads, and three young boys died after falling into an ice-covered lake as the country recorded its coldest night of the year so far. Parts of London's underground network were suspended or faced delays, while motorways were gridlocked due to snow. London's Gatwick and Stansted airports warned flight schedules could be disrupted. The Met Office issued a yellow weather warning for snow and ice in London and south-east England, with ice and fog warnings in other parts of England and the whole of Northern Ireland. Temperatures dropped below -15 degrees Celsius (5 degrees Fahrenheit) in northern Scotland, with the Met Office confirming it was the coldest night of the year. Further warnings in Scotland and north-east England for potential disruption caused by weather will start at midnight on Tuesday.<br/>
