A deadly explosion tore through a fertilizer plant and leveled dozens of homes in a small Texas town late on Wednesday, killing up to 15 people, injuring more than 160 and spewing toxic fumes that forced the evacuation of half the community.
Six firefighters, two paramedics and a police officer are confirmed dead, according to KWTX.com. Seven nursing home residents were also reported missing.
The death toll was expected to rise as search teams combed through the rubble of the West Fertilizer Co. plant and surrounding homes. Wmergency services estimated that up to 70 people may have died.
Officials said flames that continued to smolder inside the plant posed two threats - the possibility of setting off an explosion of a second fertilizer tank and the emission of hazardous fumes into the surrounding community.
Wilson said about half the town, an area encompassing eight to 10 blocks, had been evacuated and that "we might even have to evacuate on the other side of town" if winds shift overnight as expected.
The blast, apparently preceded by a fire at the plant, was reported at about 8 p.m. CDT (0100 GMT on Thursday) in West, a town of some 2,700 people about 80 miles south of Dallas and 20 miles north of Waco.
West Mayor Tommy Muska told Reuters that five or six volunteer firefighters who were among the first on the scene in the blast zone were unaccounted for.
CNN reported that at least two people had been killed, but that figure could not be independently confirmed.
Massive explosion at Texas fertilizer plant
"It's a lot of devastation. I've never seen anything like this," McLennan County Sheriff Parnell McNamara said. "It looks like a war zone with all the debris."
Wilson said 50 to 75 homes were damaged by the explosion and a fire that followed, and that a nearby 50-unit apartment complex had been reduced to "a skeleton standing up." Muska put the number of destroyed homes at between 60 and 80.
Wilson said 133 people had been evacuated from a damaged nursing home, but it was not immediately clear how many residents of the facility were hurt.
He estimated that overall more than 100 people had been injured in the disaster.
There was no immediate official word on what sparked the explosion as emergency personnel assisted victims and doused the flames. U.S. Representative Bill Flores, whose district includes West, said he doubted any foul play was involved.
"I would not expect sabotage by any stretch of the imagination," he told CNN.
The air in town remained thick with smoke hours after the explosion, and the area around the blast site was littered with shards of wood, bricks and glass.
A Texas public safety dispatcher in Waco told Reuters the explosion followed a fire that erupted at the plant. Video footage showed a large fire burning at the scene before exploding into a fireball.
The blast produced ground motion equivalent to that of a magnitude 2.1 earthquake, according to the U.S. Geological Survey.
A Reuters reporter observed that a nearby middle school and several homes were severely burned. Dallas television station WFAA reported from helicopters that a roughly three-block area of West appeared to have been flattened.
BURNS, BROKEN BONES
Jason Shelton, 33, a father-of-two who lives less than a mile from the plant, said he heard fire trucks heading toward the facility five minutes before the explosion, and felt the concussion from the blast as he stood on his front porch.
"My windows started rattling and my kids screaming," Shelton told Reuters. "The screen door hit me in the forehead ... and all the screens blew off my windows."
Hillcrest Baptist Medical Center in Waco reported treating 66 patients, including children, for injuries including lacerations, burns and broken bones.
"We are seeing a lot of lacerations and orthopedic-type injuries ... things you would expect in an explosion," said David Argueta, vice president of hospital operations.
He said nine people suffering burns had been transferred to the Parkland Hospital in Dallas. A third hospital, Providence Health Center, reported receiving more than 30 patients from the disaster.
Governor Rick Perry issued a statement saying his office had "mobilized state resources to help local authorities" deal with the incident.
A White House official said the Obama administration was aware of the situation and monitoring local and state response through the Federal Emergency Management Agency.
The explosion came two days before the 20th anniversary of a fire in nearby Waco that engulfed a compound inhabited by David Koresh and his followers in the Branch Davidian sect, ending a siege by federal agents.
About 82 members of the sect and four federal agents died at Waco.
