As Pakistan continues to seek evidence from India against terrorists, underworld dons and criminals said to be operating from its soil, authoritative Government sources here point out that Islamabad has been provided with proof, material and aide-memoires since 1985. Sources say that such evidence provided by New Delhi often contains details of sanctuary, training and equipment given by Pakistan to Sikh and Kashmiri terrorist organisations, lists of fugitives wanted by the CBI and the Army authorities, cases of Pakistan-based individuals caught trying to smuggle in arms and narcotics. Two prominent cases in which evidence was given are the Bombay serial blast of March 12, 1993, and the IC-814 hijacking of December 1999.
