Afghan provincial authorities on Sunday were investigating reports that 20 private security guards were killed in a U.S.-led coalition air strike southwest of Kabul, two officials said. U.S.-led forces called in the air strike to fend off an attack by insurgents on several posts of the local security company that guards a road construction project in the Giro district of Ghazni, a provincial government source was quoted as saying by Reuters. "According to the reports that we have received 20 people of the company have been killed in ... the coalition attack," another official said. A U.S. military spokesman said he had no information about the incident.
