Militants attack Afghan delegation at site of U.S. killings The delegation was talking with families of the victims in Balandi village when they heard shooting, Qayum Karzai, one of the president's brothers, told the Associated Press. He said he did not believe anyone was killed in the attack, but he had heard reports of one person wounded in the foot. An AP reporter accompanying the delegation said the gunfire came from two different directions. The ambush came as hundreds of students in the eastern city of Jalalabad took to the streets to protest the killing, calling on the prosecution of the solider in an Afghan court. On Monday, some members of the Afghan parliament cast doubt on the U.S. account that a lone gunman was responsible for the killings. "If the culprits are not punished, then people will be forced to take part in an uprising," lawmaker Nazifa Zaki said Monday. The slayings were the latest in a cascade of missteps and blunders that have shaken Afghans" confidence in the United States. And as ghastly details and images of the bodies were broadcast on Afghan television, even some Afghans with close ties to the United States said they feared that Sunday's killings in the Panjwai district of Kandahar province could mark an irreversible turning point. "I am concerned like never before," said Waheed Omer, the Afghan president's former spokesman, who spent years arguing that the relationship between Kabul and its Western patrons was thorny but solid and essential. It seems we only have bad choices to make. The lines between friends and enemies are blurred like never before. "Afghan blood cannot be spilled in vain," said Shukria Barakzai, a member of parliament who heads the defense committee and has had strong relationships with Western officials. Barakzai said the suspect should be tried in an Afghan court or by an international tribunal, rather than in a U.S. military court. "We really need a proper, very official court for that guy," she said. We really, really need it. The Taliban vowed to avenge the killings, which fit into its narrative depicting foreign troops as callous killers waging a war on Islam. In its statement, the militant group anticipated that the United States would seek to portray the killings as the acts of a deranged soldier. "If the perpetrators of this massacre were in fact mentally ill, then this testifies to yet another moral transgression by the American military because they are arming lunatics in Afghanistan who turn their weapons against defenseless Afghans," the Taliban statement said. To deflate anger over the killings, U.S. officials will need to act swiftly and sternly, said Davood Moradian, an assistant professor of political science at the American University of Afghanistan.
