With India accusing it of "deliberately stifling" the probe into Mumbai attacks, Pakistan on Monday said New Delhi should assist it in investigation by giving "concrete proof" instead of making allegations about its sincerity.
"India should not doubt our sincerity in handling this case. Instead of levelling allegations, they should provide us with concrete proof so that we could take this case forward in a meaningful way," Foreign Office spokesman Abdul Basit said.
Basit said Pakistan's judiciary would decide on the dossiers provided by India with information regarding the Mumbai attacks. "We want to make it clear to India that this is a purely judicial matter and the governments of Pakistan and India cannot do anything about this," he told BBC.
"Only the courts can take a decision on the dossiers," he said, adding that court proceedings had begun against five suspects arrested by Pakistani authorities in connection with the attacks. "The matter is now in the court and it is incorrect to comment on this," Basit said.
Asked about Indian Home Minister P Chidambaram's remarks about Pakistan's "unwillingness" to prosecute Laskhar-e-Taiba founder Hafiz Saeed, Basit said such comments went against the spirit of the joint statement issued by the Pakistani and Indian premiers after their meeting Sharm el-Sheikh in July.
India put its composite dialogue with Pakistan on hold in the wake of Mumbai attacks, blamed on LeT.
Chidambaram had on Saturday accused Pakistan of "deliberately stifling" the 26/11 probe.
