Taliban vows revenge after civilian slaying The NATO-led International Security Assistance Force is on high alert following the deaths. ISAF spokesperson Brigadier General Carston Jacobson admitted the shootings had made a difficult and deadly situation even more so: "We pledge to all the noble people of Afghanistan our commitment to a rapid and thorough investigation, the short time between incidents that we have seen in recent weeks, are a burden and a concern for us," he said. Anti-Americanism, is already close to fever pitch following the burning of copies of the Koran at a NATO base last month, the latest carnage pours fuel on the fire. Human rights activist Nadir Nadiri says the killings will play into the hands of the insurgents. These acts will undermine all the efforts to stabilise Afghanistan, it will also provide more tools for the insurgents to provoke people against the Afghan government and its international partners. The White House was quick to condemn the act and offer condolences to the families of the victims, but Afghan President Hamid Karzai called the murders "assassinations" and the "intentional killing of innocent victims."
