Explosion at Beechcraft plant in Wichita injures at least a dozen, officials say

Fire officials were called to the plant just after 8 a.m., KAKE-TV reported. At least one person suffered serious injuries, according to a Sedgwick County dispatch supervisor.

Chief James Fromme, of the Wichita Fire Department, said a 4-inch natural gas line was severed, the Eagle reported.

A spokesman for Wichita Mayor Jeff Longwell told CNN it was too early to know the extent of the damage at the facility. The spokesman said the plant was closed for the holidays, adding officials hoped "injuries will be minimal."

Police have blocked off the area around the plant, and an investigation is ongoing, KNSW reported.
