WASHINGTON (AFP/Reuters) - Prime Minister Yousuf Raza Gilani said Monday that Osama bin Laden was not in his country, arguing that the worlds most wanted man would not have escaped his nations military operations. The PM defended his country as a responsible nuclear power, shooting down concerns at a major security summit that extremists could seize loose weapons. He urged Washington to help ease tensions with India but said there were no plans for the rivals to meet on the sidelines of a nuclear summit. Gilanis statement goes against the conventional wisdom of many in the US intelligence community who suspect that the Al-Qaeda chief has holed himself up in Pakistans lawless areas bordering Afghanistan. Certainly he is not in Pakistan, Gilani told CNN on a visit to Washington to attend a major nuclear summit. Gilani said he had little information on Osamas whereabouts, but pointed to Pakistans assaults since last year on extremists in regions such as Swat and South Waziristan. Our military actions are very successful, Gilani said. He would have been arrested or... I even dont know whether is alive or not. Speaking earlier at a roundtable with American journalists, Gilani pledged that Pakistan would not relent in fighting the Taliban. I am not in favour of the negotiations with Taliban because at times we talk about good Taliban and bad Taliban, he said. I always believe that militants are the militants. They just want to destabilise the system. Our people have let it be known that they would not allow a handful of extremist bigots and terrorists to represent our peaceful way of life and inclusive culture, he said. The Prime Minister rebuffed calls to halt production of fissile material and insisted that Pakistan needed a deterrent against historic rival India. Instead, Gilani made a new pitch to the US - which relies on Pakistan in its campaign against extremists - to support the blackout-plagued nation in developing civilian nuclear power. I assure you that Pakistan, as a responsible nuclear state and an emerging democracy, stands with the international community in its effort to make this world a better place to live in, Gilani told a roundtable with reporters. Asked if US investigators could have access to Dr Abdul Qadeer Khan, Gilani said that chapter has been closed and denied the scientist was walking free, saying: He is actively being regulated by the judiciary. Gilani did not address the fissile material issue directly, saying only that Pakistan has discussed it with the US. For a minimum deterrence, we have to have. That is our requirement, he said of nuclear material. Gilani pledged he would not tolerate extremists using his country as a base to attack India but said he needed more evidence about a group blamed in the Mumbai attacks. Gilani confirmed that President Barack Obama raised Pakistan-India tensions including the issue of Lashkar-e-Taiba in the White House meeting Sunday, relaying concerns from Indian Prime Minister Manmohan Singh. President Obama discussed with me that he really wants ... good relations (between India and Pakistan) and certainly it is in everybodys interests to play a role, whatever they can play, to bring Pakistan and India closer, Gilani said. We dont want our soil used against any country and neither would we allow somebody elses soil to be used against Pakistan, Gilani told the roundtable with reporters. Gilani said that Pakistan has already banned what he called some extremist groups and frozen their bank accounts. He said Pakistan was seeking more evidence from India against Lashkar-e-Taiba and that the courts were examining the group, which is suspected in the 2008 siege of Mumbai that left 166 people dead. If we have more effective evidence, certainly they will be brought to justice, Gilani said. Pressed on whether Obama offered specific help on issues such as resolving the dispute over Kashmir, Gilani told reporters this was not discussed. Talking to reporters, Foreign Minister Shah Mehmood Qureshi said that diplomacy was the only way forward between the two countries and that India needed to look beyond Mumbai. We have to look beyond Mumbai. Mumbai was sad, Mumbai was tragic, but we are as much victims of terrorism as India is and so this terrorist threat becomes a common challenge, Qureshi said. He voiced concern about the attitude towards Pakistan both in Indias ruling Congress Party and the Bharatiya Janata Party (BJP), the Hindu nationalist Opposition. Prime Minister Manmohan Singh means well. We have no doubt about that, Qureshi said. But the problem is that he has not been able to carry domestic politics along within the Congress Party and the BJP, he said. The BJP has been very hawkish on him, I think unfair to him, and unfair to the region because... coexistence is the most sensible way forward, Qureshi said. FM Qureshi said Pakistan had explained to the US the three-layer security system it has put in place for its nuclear arsenal. We are confident that our system is second to none. Its world class, Qureshi said. Fortunately there has been no incident. Asked what role Washington could play in the peace process, he said: To nudge us together and to facilitate the process. Qureshi said the US - which has more than 80,000 troops in Afghanistan - would benefit from improved ties between India and Pakistan as Islamabad could shift its focus from its eastern border. The more ease we have on the eastern front, the better equipped we are to deal with the western front (Afghanistan), said Qureshi.
