The US capital and the states surrounding it have been paralysed by the worst snowstorm in decades, which started on Friday. Authorities in Washington DC and several states including - Virginia, West Virginia, Maryland, and Pennsylvania - have declared a state of emergency. More than half a metre of snow's been dumped, cutting off the power to more than a hundred thousand homes. Transportation for many is at a standstill as airports shut down and public transport systems have been severely crippled. President Barack Obama has nicknamed the storm "Snowmageddon".
