Woodward, Okla. —
Other witnesses compared the scene to something from the Iraq War or the 1995 Oklahoma City bombing, and authorities said the plant made materials similar to that used to fuel the bomb that tore apart that city's Murrah Federal Building.
Although authorities said it will be some time before they know the full extent of the loss of life, they put the number of those injured at more than 160 early Thursday. West Mayor Tommy Muska told reporters that his city of about 2,800 residents needs "your prayers."
"We've got a lot of people who are hurt, and there's a lot of people, I'm sure, who aren't gonna be here tomorrow," Muska said. "We're gonna search for everybody. We're gonna make sure everybody's accounted for. That's the most important thing right now."
In the hours after the blast, many of the town's residents wandered the dark and windy streets searching for shelter. Among them was Julie Zahirniako, who said she and her son, Anthony, had been playing at a school playground near the fertilizer plant when the explosion hit. She was walking the track, he was kicking a football.
The explosion threw her son four feet in the air, breaking his ribs. She said she saw people running from the nursing home and the roof of the school lifted into the air.
"The fire was so high," she said. "It was just as loud as it could be. The ground and everything was shaking."
The town's volunteer firefighters had responded to a call at the plant at 7:29 p.m., Swanton said. Due to the plant's chemical stockpile, "they realized the seriousness of what they had," he said.
Muska was among the firefighters, and he and his colleagues were working to evacuate the area around the plant when the blast followed about 20 minutes later. Muska said it knocked off his fire helmet and blew out the doors and windows of his nearby home.
