NATO has admitted it mistakenly killed an Afghan mother and five of her children in an air strike last week. The air strike occurred in Helmand province. The Pentagon claimed responsibility after the killings were revealed by the governor of Helmand. Meanwhile, there are reports that as many as 14 civilians were killed in another incident in northwestern Badghis province. A spokesperson for Afghan President Hamid Karzai expressed dismay Monday over the air strikes, saying they are unacceptable to the Afghan government. In related news, three U.S. soldiers were killed in eastern Afghanistan Monday.
