THE FBI today rejected claims purportedly from two Islamic extremist groups of responsibility for an oil refinery explosion in Texas

"We've been getting calls about some emails circulating apparently from people claiming responsibility for the explosion," Al Tribble, a spokesman for the FBI office in Houston, said.
"We've found no evidence to support criminal or terrorist activity," he said.

The FBI was treating the blast at the BP refinery in Texas City, south of Houston, as an accident.

Great bit of police work. I haven't seen anything solved this quickly since the Park Police wrapped up the Vince Foster suicide.
