Fuel thieves tampering with an oil pipeline could have sparked a deadly blast in central Mexico that flooded streets with fire and killed at least 27 people before dawn on Sunday, Dec. 19, 2010. The accident occurred just before 6 am (1200 GMT) when oil spilling from a breached pipeline quickly burst into a fireball that flattened homes and wrecked cars in San Martin Texmelucan, a small community in the state of Puebla about 50 miles (75 km) east of Mexico City.
