Aziz said he was personally not aware of what information had been shared with Sharif but recalled that another general had told him that Sharif had once asked during an informal discussion: "When are you giving us Kashmir?" This suggested that Sharif was not completely in the dark, Aziz said.
The former general's remarks are the first time someone from the senior military hierarchy has spoken in detail and with frankness about the Kargil conflict, the report said.
Aziz said the operation was a "failure" and the actual figure for Pakistani casualties was still not known.
"It was a failure because we had to hide its objectives and results from our own people and the nation. It had no purpose, no planning and nobody knows even today how many soldiers lost their lives," he said.
