Late in the afternoon of June 10, during a firefight with Taliban militants along the Afghan-Pakistani border, American soldiers called in airstrikes to beat back the attack. The firefight was taking place right on the border itself, known in military jargon as the “zero line”. Afghanistan was on one side, and the remote Pakistani region known as the Federally Administered Tribal Areas, or FATA, was on the other. The stretch of border was guarded by three Pakistani military posts.

The American bombers did the job, and then some. By the time the fighting ended, the Taliban militants had slipped away, the American unit was safe and 11 Pakistani border guards lay dead. The airstrikes on the Pakistani positions sparked a diplomatic row between the two allies: Pakistan called the incident “unprovoked and cowardly”; American officials regretted what they called a tragic mistake. But even after a joint inquiry by the US, Pakistan and Afghanistan, it remained unclear why American soldiers had reached the point of calling in airstrikes on soldiers from Pakistan, a critical ally in the war in Afghanistan.

The mystery, at least part of it, was solved in July by four residents of Suran Dara, a Pakistani village a few hundred yards from the site of the fight. According to two of these villagers, whom I interviewed together with a local reporter, the Americans started calling in airstrikes on the Pakistanis after the latter started shooting at the Americans.

“When the Americans started bombing the Taliban, the Frontier Corps started shooting at the Americans,” we were told by one of Suran Dara’s villagers, who, like the others, spoke on condition of anonymity for fear of being persecuted or killed by the Pakistani government or the Taliban. “They were trying to help the Taliban. And then the American planes bombed the Pakistani post.”
