Storm kills at least six on highways

Biggest accident in Baltimore as tanker skidded off the road and exploded

A winter storm of snow, freezing rain and bone-chilling temperatures socked the nation's mid-section and East Coast on Saturday, causing hundreds of accidents on icy roads and putting a crimp on Christmas shopping.

At least six deaths were blamed on the slick roads and authorities were investigating a few other traffic fatalities as possibly weather-related. Perhaps the biggest accident happened in Baltimore, when a tanker carrying gasoline skidded off a highway and exploded, authorities said.
