Pittsburgh (PPI) - Indian Prime Minister Manmohan Singh asked Pakistan to 'give up its attitude of using terror as an instrument of state policy as that was the only obstacle in normalising relations with its neighbour. 'Indias message is that India seeks to normalise its relationship with Pakistan. But the only obstacle is that it should shed its old attitude of using terror as a state policy, he said at a post G-20 summit news conference here. Singh reiterated Indias demand that Pakistan should take action against those involved in 26/11 Mumbai terror attacks, saying that if Islamabad took proper action, India would move the extra mile to normalise relations. 'We have supplied our material and evidence for them to carry out investigation. Although tragedy took place in India, conspiracy took place in Pakistan. Pakistan has admitted to this. We want them to bring to book the culprits involved in Nov 26 attacks. He said there was no change in Indias stand on Pakistan since the Sharm-el-Sheikh talks with his counterpart Yousuf Gilani, a position he has made clear in Indian parliament. 'If you read my statements in parliament, I have explained the govts position. I think there is no change on this, he said when asked how he looked forward to moving ahead with relations with Pakistan. 'India and Pakistan are neighbours and they have an obligation to move as neighbours.
