Megantic death toll rises to five 7 July 2013 Last updated at 18:49 Another two bodies have been found after a runaway train carrying crude oil exploded in the Canadian town of Lac-Megantic, police say. The death toll from Saturday's blast stands at five; there are fears it will rise further as 40 people are missing. The pre-dawn explosion sent a fireball and black smoke into the air, forcing the evacuation of 2,000 people. Police are trying to account for dozens of missing people - popular bars near the blast site were said to have been crowded at the time. "There are about 40 people, more or less, who are considered to be missing," police spokesman Michel Brunet told reporters. There could be more, there could be less. Police said earlier they expected the death toll to rise, but were checking whether people reported missing were simply away on holiday. 'It's a mess' Two of five cars that exploded are still ablaze nearly 36 hours later, Lac-Megantic Fire Chief Denis Lauzon told reporters on Sunday morning. Firefighters have been battling the flames with water and a fire retardant, but are staying at least 1,000 ft from the burning tankers for fear of more blasts, he added. About 30 buildings - including some of the town's most historic structures - were obliterated by the blast. "We lost the bibliotheque [library] which had all the memories of people here - it's a mess," said Chief Lauzon. People whose homes have been badly damaged are being sheltered at a nearby school. Fire Chief Denis Lauzon: "We still have a risk of explosions as we still have tankers on fire" The train's 73 cars carrying pressurised containers of crude oil reportedly uncoupled from an engine parked outside the town around 01:00 (06:00 BST) on Saturday, gathering speed as they rolled down the tracks before derailing in Lac-Megantic. Eyewitnesses said that by the time the cars reached the town they were travelling at considerable speed. Bernard Demers, who runs a restaurant near the blast site, said the fireball that followed the derailment was "like an atomic bomb," the Sunday Telegraph reported. The Montreal, Maine & Atlantic train had five locomotive engines and was parked in the village of Nantes - about 7km (four miles) from Lac-Megantic - during an overnight driver shift-change, said a company spokesman. A driver had parked the train and put the brakes of its engines on "properly" before going to a local hotel for the night, said the spokesman, Joe McGonigle. But the fuel cars somehow became uncoupled, causing them to roll downhill into the town and derail, he added. A lakeside town that is home to some 6,000 people, Lac-Megantic is close to the US border with Vermont and 130 miles north of Maine's capital, Augusta.
