BAGHDAD, Iraq (AP) - A gas explosion -- and not a bomb -- is now being blamed for a series of deadly blasts leaving at least 47 dead in Baghdad.
U-S military officials say their experts can find "no evidence" of anything other than what they describe as a "significant gas explosion."
But Iraqi officials have their own ideas. Even the prime minister's office put out a statement saying the attack started with a number of rockets, followed by a car bomb, then more rockets and a bomb. The U-S military, though, says there's no residue from rockets.
