UNITED NATIONS - Prime Minister Manmohan Singh on Saturday reaffirmed Indias commitment to fight terrorism on all fronts, saying there should be no 'selective approach. Addressing the 66th session of UN General Assembly, the Indian PM said he was encouraged by his countrys security cooperation with Bangladesh. He made no mention of Pakistan in his 20-minute address. Outside the UN building, hundreds of Kashmiris and Sikhs, who wore yellow turbans, held separate demonstrations accusing India of state terrorism, grave violation of human rights and discrimination of minorities. A third group - a tiny one - also stood with placards of support for Sonia Gandhi, her son, Rahul, and Manmohan Singh. Dealing with the situation in the region, the Indian leader said: In South Asia there are encouraging signs of cooperation in the area of security, as exemplified in Indias cooperation with Bangladesh. Such cooperation is adding to the security of both our countries. On terrorism, Singh said there cannot be 'selective approaches in dealing with the scourge that needed to be fought across all fronts. He noted that terrorism continues to rear its ugly head and take a grievous toll on innocent lives. Developing countries need a peaceful external environment to grow, Singh told the world leaders assembled for the annual meeting. The fight against terrorism must be unrelenting. There cannot be selective approaches in dealing with terrorist groups or the infrastructure of terrorism. Terrorism has to be fought across all fronts, he said. In this context, the prime minister referred to the assassination of former Afghan President Burhanuddin Rabbani and said it was a 'chilling reminder of the designs of the enemies of peace in Afghanistan. He said it was essential that the process of nation-building and reconciliation in Afghanistan succeeds, which was vital for enduring peace and security in the region. India will play its part in helping the people of Afghanistan to build a better future for themselves, just as we are doing in other countries in South Asia, he said, adding: We will do so because prosperity and stability in our region are indivisible. On UN Security Council reforms, he said unless comprehensive reform is undertaken, the process would only be piecemeal and incomplete. India would, along with members of the G4 (Brazil, Japan and Germany), continue to work pro-actively to maintain the momentum for Security Council reforms, he said. The G-4 has so far failed in their bid for permanent seats in an expanded Security Council.
