Afghan President Hamid Karzai has warned that NATO troops fighting in Afghanistan risk becoming “occupying” forces if they don’t stop air assaults on civilian homes as they target militants. Speaking to reporters in Kabul on Tuesday, Karzai said, “From this moment, air strikes on the houses of people are not allowed. The people of Afghanistan so far have endured casualties and have given sacrifices. So these operations should not be used against Afghan people and their houses.” The remarks came just days after the president gave a “last warning” to NATO over civilian deaths after an air assault killed 14 civilians on Saturday, including children and women. However, the coalition forces maintain such aerial raids are essential.
