One Isaf source voiced concern that the Pakistani intelligence agency, the ISI, could go much further and use its suspected influence over insurgent groups in the tribal areas along the Afghan border to launch reprisal attacks on Nato. "This will come back at us, and at a time and a place of their [the ISI's] choosing," the source predicted. In September the chairman of the US joint chiefs of staff, Admiral Mike Mullen, said the ISI was using insurgent groups such as the Haqqani network to wage a "proxy war" in Afghanistan.
