Tensions Between Afghanistan and U.S. Increase as Airstrike Kills Civilians KABUL, Afghanistan - A coalition airstrike in a province north of Kabul killed at least two Afghan villagers on Wednesday morning, prompting President Hamid Karzai to order an official inquiry and escalating tensions yet again between the allies over civilian deaths. While details of the fighting in the Seya Gerd district of Parwan Province remained sketchy, officials confirmed that a strike had been called in after Afghan and coalition Special Operations advisers took heavy fire during a mission to clear the area. The gunfight, which took place in an insurgent stronghold used to carry out attacks on Bagram Air Base, claimed the life of one coalition soldier, at least 10 Taliban fighters and several civilians, though the exact number was not yet clear, coalition and Afghan officials said. Civilian casualties have always been a contentious issue in Afghanistan, but perhaps never more so than now. With the fate of a long-term security deal between the United States and Afghanistan hanging in the balance, Mr. Karzai has made a cessation of the airstrikes a precondition of any agreement. In late November, after a drone strike claimed the lives of civilians in southern Helmand Province, the president all but threatened to cancel the deal. The civilian deaths on Wednesday are likely to worsen the relationship between the Afghans and Americans, a partnership that seems to grow more strained with every passing week. Mr. Karzai's recent order to release dozens of prisoners believed to have killed American forces, despite weeks of threats of a troop withdrawal by the United States, caused the latest dispute between the allies. A spokesman for Mr. Karzai, Aimal Faizi, said eight civilians had been killed in the airstrike. "Of course, this is exactly about one of our conditions about the signing" of a long-term security agreement, he said, "but it seems like it is not understood. How many more innocent Afghans have to die so it gets the attention of U.S. officials? So heavy is the tension over the issue of civilian casualties that, after the episode in Parwan, the presidential palace, the coalition and even the Taliban released statements giving it their own spin. The palace said it had appointed a fact-finding delegation that would report back with details in three days. The coalition, in addition to offering an apology for any civilian casualties, sought to offer context to the "Afghan-led" operation in its statement. "This deliberately planned clearing operation was conducted to disrupt insurgent activities in the district, including attacks on Bagram Air Field, and in support of Afghan National Security Forces" tactical priorities," the statement said. Local district and provincial officials were informed in advance of the operation and were provided updates during and after the actions. The Taliban, for their part, seized the opportunity to score a propaganda point. While the Taliban spokesman, Zabiullah Mujahid, sent a note to reporters saying that his email address had been hacked "by the enemy," the insurgent group managed to put out a brief statement about the deaths. "Last night foreign and local forces targeted and bombed civilian homes," the statement said. Four children and two women were martyred, and a number of them were wounded. The misery is still going on. The Seya Gerd district of Parwan, and the neighboring Wazghar Valley, has been a hotbed of the insurgency for the last few months, according to Afghan officials. Taliban fighters frequently attack the local police in the area, and it is believed that several recent attacks on Bagram Air Base were carried out from the area. Aziz Ahmad Zaki, a spokesman for the governor of Parwan, said that the coalition Special Operations advisers had come to assist the Afghan forces in the area, setting up alongside them in a district check post that quickly came under fire from Taliban attackers on Tuesday. Around 6:30 a.m. Wednesday, Afghan and coalition forces began a clearance operation in the Wazghar Valley, but ran into a Taliban ambush, taking fire from several compounds in the area at once, officials said. "Afghan and coalition forces returned fire and required defensive air support to suppress the enemy fire," according to the coalition statement. "The insurgents in this area enjoy freedom of movement allowing them to harass and threaten the local population as well as stage and facilitate attacks," the statement said. Tragically, two civilians inside a building from which insurgents were firing on the commandos were killed. The fallout from the deaths remains to be seen. The early statement from the presidential palace was measured when compared with the outrage expressed after the civilian deaths in Helmand in late November. At the time, the president threatened to cancel the long-term security deal if such "arbitrary acts and oppression of foreign forces continue." An earlier version of this article misidentified the leading cause of civilian casualties in Afghanistan. Most civilians are killed by improvised explosive devices, not by airstrikes by coalition forces.
