LAC-MEGANTIC, Quebec (July 8, 2013)--Hazardous conditions Monday were hampering the efforts of firefighters to search for some 40 people still missing after the explosion of a runaway oil tanker train over the weekend in Quebec in which at least five others were killed.
The search was halted overnight because of the dangerous conditions.
A police spokesman said only a small part of the devastated scene has been searched, as firefighters make sure all of the flames are out.
Many of the missing are believed to have been drinking at a popular downtown bar when the runaway train derailed, causing explosions and a massive fire.
Searchers still haven't been able to reach that area.
Monday, firefighters are focusing their efforts on two rail cars filled with oil, dousing them with water and foam, to try to keep them from overheating and exploding.
All but one of the train's 73 tanker cars were carrying oil when they somehow came loose Saturday morning.
They sped downhill nearly seven miles into a town near the border with Maine and derailed.
At least five of the cars exploded.
About a third of the 6,000 residents were forced from their homes by the explosion and flames.
