Nato service members killed by Afghan soldier inside British base A Western official in southern Afghanistan confirmed that the incident happened at the main NATO base in Lashkar Gah, Helmand province, but declined to give further information. The official spoke on condition of anonymity because the information had not been officially released. Tensions between the US and Afghanistan have been particularly strained following the burning of Korans at a US base in February. That act - which US officials have said was a mistake - sparked riots and attacks that killed more than 30 people, including six American soldiers. Afghans have also expressed outrage at the March 11 shooting spree allegedly by a US soldier in which at least 16 villagers were killed, although the incident has not sparked the same level of public protests. The Lashkar Gah base is dominated by British forces. The Ministry of Defence said it was aware of the incident, but refused to release any more details or confirm whether the soldiers were British.
