US says blasts in Baghdad were gas explosion

The US military Monday said a series of blasts that killed at least 47 people in a mostly Shi'ite neighborhood was caused by a gas main explosion, but the Iraqi government insisted the area was hit by rockets and car bombs. US ordnance experts found "no evidence" of anything other than a "significant gas explosion," US spokesman Maj. Gen. William B. Caldwell said. "There is nothing that we have been able to find that would attribute to anything other than gas main explosion and subsequent explosions associated with that one," he said.
