The New York Times reports CIA has evidents that Pakistan spy service is aiding militants on the Afghanistan border From NYT:
'The C.I.A. emissary presented evidence showing that members of the spy service had deepened their ties with some militant groups that were responsible for a surge of violence in Afghanistan, possibly including the suicide bombing this month of the Indian Embassy in Kabul, the officials said. ..'The decision to confront Pakistan with what the officials described as a new C.I.A. assessment of the spy service's activities seemed to be the bluntest American warning to Pakistan since shortly after the Sept. 11 attacks about the ties between the spy service and Islamic militants. ...'The C.I.A. assessment specifically points to links between members of the spy service, the Directorate for Inter-Services Intelligence, or ISI, and the militant network led by Maulavi Jalaluddin Haqqani, which American officials believe maintains close ties to senior figures of Al Qaeda in Pakistan's tribal areas.'
