In this image released by Quebec provincial security, Surete du Quebec, shows fires burning in Lac-Mégantic, around 250 kilometers (155 miles) east of Montreal after a train derailment on July 6, 2013. Explosions rocked the small town in Quebec and several people were still missing after an oil-laden cargo train derailed in the middle of town early Saturday. The accident created a spectacular fireball, witnesses said, and the flames were still not under control hours later.
