New Delhi - Indian Prime Minister Manmohan Singh Saturday asked Pakistan to hand over the perpetrators of Mumbai terrorist attacks so that they can be tried in India.

Mentioning that "war is no solution" to the problems between India and Pakistan, Singh hoped "better sense" would prevail on the Pakistan leadership and it would recognize that those behind the Mumbai carnage had to be brought to justice.

"It (Pakistan) has to take action on the demand from all civilized countries that the perpetrators (of Mumbai attacks) will be brought to book," Singh told a press conference in the north-eastern Shillong town.

"We hope that these criminals will be handed over to us to face trial," he said.

"We are making every possible effort to ensure that all those involved in the atrocities should be handed over. Pakistan should recognize that this is an area where maximum possible cooperation is required," Singh told reporters.

New Delhi believes that the Pakistan-based Lashkar-e-Taiba was behind the November 26 attacks which left at least 170 people dead and has demanded the extradition of militant leaders and criminals.

Pakistan has so far rejected India's plead to extradite the suspects. Pakistan Foreign Minister Shah Mahmood Qureshi said Islamabad had no extradition treaty with India and handing over Pakistani nationals was not possible.

Singh also called upon the new government in neighbouring Bangladesh to cooperate in acting against anti-India militants based on its territory.

"Successive governments in Bangladesh did not cooperate with us to evict Indian militant bases from that country, but I hope that the new prime minister-elect Shiekh Hasina would take appropriate measures not to allow their territory to be used by militants," he said.

Indian security agencies have blamed Bangladesh-based militant outfits like the Harkat-ul Jehadi Islami (HuJI) and rebel groups for attacks in its north-eastern region.

In the worst-terrorist strike in India's north-east, over 90 people were killed in bombings across the north-eastern Assam state in October last year.

In a related development, US envoy to India David Mulford met Federal Home Minister P Chidambaram to the backdrop of Washington's offer to work with New Delhi following the Mumbai attacks.

The meeting took place amid reports that Delhi was compiling evidence about the role of Pakistan-based elements in the Mumbai terrorist attacks to share it with major countries.

The evidence, includes the confession of Ajmal Amir Kasab, the captured terrorist in Mumbai attacks, records of satellite phone used by the attackers and transcript of conversations between the attackers and militant leaders in Pakistan, government sources told local media. (dpa)
