Cadaver dogs were searching early Wednesday through the rubble of a U.S. restaurant flattened by a natural gas explosion, and authorities said 14 people were injured - two critically, according to AP. Kansas City Fire Chief Paul Berardi said the search was standard given the size of the fire and the fact that there was no immediate, reliable count of people who were inside at the time. "I would always fear there are fatalities in a scene like this," Berardi said. Berardi said one person reported missing, a female employee, had not been found. Missouri Gas Energy, the utility that supplies the area, said in a statement that "early indications are that a contractor doing underground work struck a natural gas line." Seven people remained hospitalized Wednesday. -- SPA
