A judge on Sunday delayed court-martial proceedings for a second U.S. Army sniper accused in the deaths of two unarmed Iraqi civilians a day after a military panel sentenced a 22-year-old specialist to five months in prison for his role in the crimes. Jorge G. Sandoval also received a reduction in rank to private and a forfeiture of his pay after he was convicted Thursday of planting evidence on one of the unidentified Iraqis who died last spring. He was acquitted of two murder charges. Sectarian violence, meanwhile, claimed at least 40 more lives Saturday across Iraq, with a flurry of attacks around the northern city of Mosul, where bombs, gunmen and mortar fire killed 14. Two U.S. soldiers were killed by gunfire, one in Diyala province north of Baghdad and one in a southern district of the capital, the Associated Press reported.
