At a conference on combating terrorism here, Durrani, who was the NSA during 26/11 terror attacks, said he had approached his Indian counterpart M K Narayanan and suggested to him about sending Pakistani investigators to India for a probe.
"He never got back on my proposal possibly because of the mistrust between the two countries," Durrani, who was sacked by the Pakistan government, said at the conference being organised by the Institute for Defence Studies and Analyses.
The government had said that the Pakistan government would also allow Indian investigators to carry out probe in their country on a "reciprocal basis", but the visit has not been finalised so far.
