About 40 people were still missing a day after a runaway train derailed in Quebec, igniting explosions and fires that destroyed a busy downtown district and killed five people.
Police said a higher death toll was inevitable, and authorities feared the number might soar once they're able to reach the hardest-hit areas. Worries remained over the status of two oil-filled train cars.
Canadian Prime Minister Stephen Harper compared the area to a war zone and said about 30 buildings were incinerated. Quebec provincial police Sgt. Benoît Richard said only a small part of the devastated area had been searched Sunday, more than a day since the accident, because firefighters were making sure all fires were out.
The train's 72 oil-filled tanker cars somehow came loose early Saturday morning, sped downhill nearly seven miles (11 kilometers) into the town, derailed and began exploding one by one. At least five exploded.
The eruptions sent residents of Lac-Megantic scrambling through the streets under the intense heat of towering fireballs and a red glow that illuminated the night sky. The district is a popular area packed with bars that often bustles on summer weekend nights. Police said the first explosion tore through the town shortly after 1 a.m. local time. Fire then spread to several homes.
Two tanker cars were burning Sunday morning, and authorities were still worried about them Sunday evening. Local Fire Chief Denis Lauzon said firefighters were staying 500 feet (150 meters) from the tankers, which were being doused with water and foam to keep them from overheating.
