Pakistan on Monday claimed that its own probe into the Mumbai attacks had made progress and it was prepared to uncover full facts about the terror strikes even as it accused India of refusing to cooperate in investigations into the heinous crime. Describing as most unfortunate Prime Minister Manmohan Singh's comments about the involvement of Pakistan's official agencies in the 26/11 attacks,his Pakistani counterpart Yousuf Raza Gilani said Islamabad's own probe had made progress and it was prepared to take forward the information provided by New Delhi to uncover the full facts. "Indian Prime Minister Dr Manmohan Singh,instead of reciprocating Pakistan's sincere sentiments to move forward towards establishing good,cooperative and friendly relations,has given a statement yesterday while addressing a meeting of chief ministers raising serious allegations in connection with the Mumbai attacks which is most unfortunate," Gilani said. "Our own investigations into Mumbai have progressed. We have received some information of an interim nature on Indian investigations. We are prepared to take this process forward with a view to uncovering full facts,thus ensuring that the perpetrators of this heinous crime whosoever they may be are brought to justice," he added. Pakistan had not only made constructive proposals for mutual cooperation but also initiated actions and investigations on its own since November 26,when he attacks began in India's financial hub,Gilani said in a statement issued by the Prime Minister's media office. "We are convinced that the only effective way of dealing with the common challenge of terrorism is to develop robust cooperation encompassing all relevant departments," Gilani said. "India has not only refused to cooperate in the investigations pertaining to Mumbai but has chosen to undertake a media and diplomatic offensive against Pakistan. It is clearly unhelpful to any serious and objective investigations and amounts to unnecessarily whipping up tensions in South Asia," he said. Gilani expressed "Pakistan's earnest desire to work towards building friendly and cooperative relations with India". He said he had great personal regard for Prime Minister Singh and was hopeful that he will act with a great sense of responsibility in the larger interest of peace,security and prosperity of the peoples of South Asia. Addressing a conference on internal security in New Delhi on Tuesday,Singh had said the evidence gathered by investigators showed that some official agencies of Pakistan had backed the Mumbai attacks. India has blamed the Lashker-e-Toiba terror group for planning and executing the attacks that killed over 180 people. Pakistan,which has said it is examining information provided by India in a dossier two days ago,wants the two countries to carry out a joint probe into the incident.
