Pakistanis Aided Attack in Kabul, U.S. Officials Say

By MARK MAZZETTI and ERIC SCHMITT

WASHINGTON — American intelligence agencies have concluded that members of Pakistan’s powerful spy service helped plan the deadly July 7 bombing of India’s embassy in Kabul, Afghanistan, according to United States government officials.

The conclusion was based on intercepted communications between Pakistani intelligence officers and militants who carried out the attack, the officials said, providing the clearest evidence to date that Pakistani intelligence officers are actively undermining American efforts to combat militants in the region.
