A US - led airstrike has killed at least 16 Afghans, including eight women and children, in the eastern province of Kunar, officials say.According to the provincial governor, 16 people - 12 of them civilians - lost their lives in the strike. Among the victims are four children and four women. The latest deadly US-led drone attack occurred in the Watapur district of Kunar Province, which lies near the border with Pakistan. A NATO spokeswoman, however, said that only enemy forces were killed in the operation. The aerial attack comes one day after at least four people lost their lives in two separate airstrikes by US-led foreign forces in Afghanistan’s central province of Wardak. Civilian killings at the hands of US-led forces have been a source of tension between Kabul and Washington in recent years. The attacks have also increased anti-American sentiment among Afghans, who hold regular protests to condemn them. The United States and its allies invaded Afghanistan in October 2001 as part of Washington’s so-called war on terror. The offensive removed the Taliban from power, but insecurity continues to rise across the country, despite the presence of thousands of US-led troops.
