KOLKATA (Agencies) - India on Saturday said that Pakistan should hand over terrorists wanted by New Delhi immediately and take concrete steps against elements spreading terror. "Pakistan has to hand over those using its soil to spread terror in India and award exemplary punishment to those directly involved in the Mumbai attacks on November 26," Indian External Affairs Minister Pranab Mukherjee said on Saturday. Mukherjee told reporters at the inaugural function of a college near Kolkata. Mukherjee said that India had on a number of occasions demanded immediate handover of those using Pakistani soil to carry out terrorist activities and now it had to act as per international demand. He said talks were on at the diplomatic level between India and Pakistan to have a joint anti-terror mechanism, adding we demand that "Pakistan crush terrorists and punish those who are now taking shelter in their territory. There are talks going on at the diplomatic level between India and Pakistan to implement a joint anti-terror mechanism, but it's hardly been implemented so far," "I hope Pakistan will now come forward and fulfil the commitment they made during the visit of their presidents Pervez Musharraf in Jan 6, 2004 and Asif Zardari in Sept 24, 2008 to India. Pakistan had promised to India not to allow any terrorist activity within its geographical region," he said. Mukherjee said: "We placed a two-point demand to Pakistan. First is to hand over a few terrorists who were involved in such extremist attacks in our country. We also demanded that Pakistan sniff out those terrorists and punish those who are now taking shelter in their territory," he said, adding all the countries should unitedly fight against terror. Opposing the misinterpretation of the terrorism issue, he said: "Some people often call it 'Islamic terrorism'. I don't believe that terrorism has connection with any religion." Meanwhile in an interview with CNN-IBN, Pranab Mukherjee said India is ready to share any information and evidence with Pakistan once investigations into the Mumbai terror attack are over. He said that India will provide whatever information is necessary. "Whatever evidences we had we can make available, but in this case you know we are still investigating. We have not come to any conclusions. Therefore at this juncture it might perhaps be premature to share the evidences." He further said "We have shared the evidences in the past. The point which I am repeating is that it has not been followed up and taken to its logical conclusion." On the question of the extradition of wanted persons like Maulana Masood Azhar, Mukherjee said India wants arrest of Pakistani citizens allegedly involved in terrorist activities and try them as per Pakistani laws. "What I have told them - there are two categories of people involved. Some people who have committed crimes in India - they have left India and taken shelter in Pakistan, like Dawood Ibrahim. We are asking the Pakistan authority to hand over persons like these to Indian authorities so that they can be tried as per Indian laws. There are persons who are Pakistani citizens who are indulging in terrorist activities let them be arrested, let them be tried as per Pakistani laws," he said. "One person I am particularly mentioning - that is Masood Azhar, he was in Indian custody. We had to hand him over to the hijackers of the Indian Airlines IC 814 plane in Kandahar. He is available in Pakistan more than often," said Mukherjee. He said "non-state actors" are operating on Pakistani soil and that was why he had used phrase "elements from Pakistan." Mukherjee said he cannot be more specific unless definitive conclusion is arrived by the investigating agencies. In response to the demarche issued by India, Pakistan said it was considering various aspects on action to be taken and planning to send a high-level delegation to India. Meanwhile, India on Saturday piled new pressure on Pakistan to crack down on militants in the wake of the Mumbai attacks, with Prime Minister Manmohan Singh citing a "moral duty" to combat terrorism. In an apparent reference to Pakistan, Indian prime minister said that governments in South Asia "have a moral duty to act firmly and quickly" against terrorists. Addressing an international conference of jurists in New Delhi, the Indian prime minister said there was a growing awareness "in our region ... that terrorism and extremism pose a threat to democracy and development. "Governments and authorities in our region and elsewhere have therefore a moral duty to act firmly and quickly." The comments came after Pakistan arrested dozens of members of the charity Jamaat-ud-Daawa, suspected of being a front for group Lashkar-e-Taiba (LeT) - which India blames for last month's attacks on its financial hub. Pakistan has placed the charity's leader Hafiz Saeed under house arrest and ordered its assets frozen after the UN Security Council listed it as a terror group following the Mumbai attacks that left 172 people dead, including nine gunmen. "The forces of terrorism, inspired by ideologies of hatred, intolerance and exclusion, pose today a fundamental challenge to liberal democracies," Manmohan said. "They pose a challenge to democracy at home, to democracy in our region, to democracy around the world. "In certain circumstances, states are both entitled and obliged to take steps that seems to derogate from human rights principles... Certain rights and freedoms can be derogated from, but only to the extent necessary to meet the security threat." New Delhi had previously blamed "elements in Pakistan" for being behind the 60-hour siege that ended on November 28, raising tensions between the two nuclear-armed South Asian rivals. US Secretary of State Condoleezza Rice has said "non-state actors" operating on Pakistani soil were responsible for the attacks.
