Forty Missing in Canadian Oil Train Crash

At least five killed

Hazardous conditions hindered firefighters' attempts Monday to search for some 40 people still missing after a runaway oil tanker train exploded over the weekend, killing at least five people, officials said.

Meanwhile, crews worked to contain oil spilling in the Claudiere River which feeds into the St. Lawrence.

The Quebec government issued a statement saying the leak was "serious, but under control." The statement said the oil could spread as far as Quebec City.
