The head of Interpol said on Sunday that Pakistan had agreed to provide DNA profiles and other data on suspected terrorists it obtained during a probe into the Mumbai attacks.
"Pakistan's Federal Investigation Agency (FIA) will send Interpol the DNA profiles that it obtained during its investigation," Interpol Chief Ronald Noble told a news conference after talks with Pakistani officials.
Interpol is a global organisation that facilitates cooperation among police forces of member countries.
The profiles will be compared against the "world's only global DNA database containing more than 83,000 DNA profiles," he added.
"Information exchanged through the Interpol data could not only result in potential breakthroughs in the Pakistani investigation but will also help other police forces protect their citizens from terrorist attacks," he observed.
Noble said he would like India also to provide similar details.
"In order for these comparisons to be complete India will be required to send Interpol the DNA profiles that they obtained in their investigation."
The Mumbai attacks that left 165 dead have been blamed by New Delhi on the Pakistan-based militant group Lashkar-e-Taiba (LeT).
The November 26-29 siege soured a five-year peace process between the nuclear-armed South Asian rivals.
Both LeT and Pakistan have denied any involvement but Islamabad admitted last month for the first time that the strikes were partly planned on its soil.
Pakistan said it had filed a case against eight people suspected of a role in the siege, and that six of them were in custody.
The FIA has already given Interpol a copy of its investigation report into the Mumbai attacks, which Noble said his organisation was grateful for.
"For the first time in the three months since those deadly attacks occurred, Interpol has received police information of paramount importance," he said.
"For the first time we have police information on those who planned, facilitated and funded those attacks," he said.
"For the first time, we have detailed information about telephone numbers, bank accounts used in terrorist financing as well as Internet addresses and the equipment and material used to perpetrate these attacks," he said.
"Already Pakistan's FIA has established links to seven countries including India and countries in the heart of Europe and the Middle East," he added.
