U.S. military spokesman Major General William Caldwell says American explosives experts found no evidence of anything other than a significant gas explosion that also set off subsequent blasts.
Iraqi Prime Minister Nouri al-Maliki has said terrorists with a deep hatred of his country carried out a wave of attacks Sunday on a Shi'ite neighborhood of Baghdad.
Mr. Maliki said the attackers, suspected Sunni insurgents, want to incite sectarian fighting in Iraq.
