Former Pakistan Army [Images] officers and those from the powerful ISI helped train the attackers who targeted Mumbai last week killing over 180 people, a media report said today quoting a former Pentagon official.

However, no specific links had been uncovered yet between terrorists and the Pakistani government, the unnamed official said, according to the New York Times.

"A former Defense Department official said on Wednesday that American intelligence agencies had determined that former officers from Pakistan's Army and its powerful Inter Services Intelligence agency helped train the Mumbai attackers," the paper said.

It, however, did not identify the official, saying he had spoken on condition of anonymity.

The disclosure came as Secretary of State Condoleezza Rice [Images] held meetings with Indian leaders in New Delhi [Images] and Admiral Mike Mullen, chairman of the Joint Chiefs of Staff,

met their Pakistani counterparts in Islamabad [Images], in a two-pronged effort to pressure the country to cooperate fully in tracking down the perpetrators of the bloody attacks, the paper said.

Pakistan has refuted Indian allegations that militants operating from its soil were responsible for the deadly attacks, with President Asif Ali Zardari [Images] terming them as "non-state actors".
