CHICAGO (AFP) - A bomb was discovered Wednesday on a natural gas pipeline in rural Oklahoma and was removed and rendered harmless without incident, officials said. "At this time we don't have any leads or anybody taking claim for placing the device on the pipeline," FBI spokesman told AFP. The bomb has been sent to a lab for testing to determine whether its contents were active or inert, but it appeared to be an "actual device" Simmonds said. "I don't know how devastating of a device it would have been," he said. "I don't know if it would have penetrated the pipeline, or just caused a big black ring around the pipe."
