SABARI, Afghanistan — As targeted killings have risen sharply across Afghanistan, American and Afghan officials believe that many are the work of counterintelligence units of the Haqqani militant network and Al Qaeda, charged with killing suspected informants and terrorizing the populace on both sides of the Afghanistan-Pakistan border.
Military intelligence officials say that the units essentially act as death squads and that one of them, a large group known as the Khurasan that operates primarily in Pakistan’s tribal areas, has been responsible for at least 250 assassinations and public executions.
Another group, whose name is not known, works mainly in Afghanistan and may be responsible for at least 20 killings in Khost Province over the summer alone, including a mass beheading that came to light only after a video was found in the possession of a captured insurgent. The video shows 10 headless bodies evenly spaced along a paved road, while their heads sit nearby in a semicircle, their faces clearly visible.
One chilling case attributed to the second death squad came after American forces captured the senior Afghanistan-based leader for the Haqqanis, Hajji Mali Khan, and killed his top deputy this summer. Just days later, the bodies of two men accused of helping the Americans turned up near the village where Mr. Khan was captured. Scalding iron rods had been shoved through their legs. One victim had been disemboweled, and both had been shot through the head and crushed by boulders. Fear shot through the entire village.
“You could hardly recognize them,” said a witness who viewed the bodies.
Across Afghanistan, assassinations have jumped 61 percent, to 131 reported killings, through the first nine months of this year, compared with the same period in 2010, according to NATO statistics. United Nations officials say they began noticing a sharp increase in 2010, with 462 assassinations according to their records, double the number from the previous year. The figures may not include many killings in remote areas, like the mass beheading, because fearful villagers never reported them.
