A published report says the CIA has confronted senior Pakistani officials with evidence that members of the country's spy service have deepened their ties with militant groups.
The New York Times says a top CIA official traveled to Islamabad this month with new information about ties between Pakistan's Inter-Services Intelligence agency and militants operating in Pakistan's tribal areas.
The militants are believed responsible for a surge of violence in Afghanistan, possibly including the suicide bombing this month of the Indian Embassy in Kabul.
Pakistan is a vital ally of the U.S. in the war on terrorism. The CIA has depended heavily on the I-S-I for information about militants in Pakistan despite long-standing concerns about divided loyalties within the Pakistani spy service.
