ISLAMABAD - Prime Minister Syed Yousuf Raza Gilani called President Asif Ali Zardari by telephone on Saturday night in Dubai and discussed with him frequent violations of country's airspace and incursions by the US forces. Both the leaders had unanimity of views that the sovereignty and territorial integrity of the country should be respected at all costs. "Prime Minister Syed Yousuf Raza Gilani called the President of Pakistan... last night in Dubai and discussed with him the frequent violation of the country's airspace and incursions by the US forces," said a statement, issued by Gilani's office. Both leaders vowed to defend Pakistan, the statement added. Agencies add: Highlighting the need for launching 'a new dialogue' to tackle terrorism, President Asif Ali Zardari has said that he would seek an international conference on the issue at the UN General Assembly later this month. "Whatever medicine we've been using it hasn't ended the poison, it's made it worse," Zardari was quoted as saying by The Sunday Times. It was earlier supposed to be a private visit to take his daughter Bakhtawar to Edinburgh University. But now, he will hold meetings with British Prime Minister Gordon Brown and Foreign Secretary David Miliband. At the UN general assembly later this month in New York, Zardari said he would call for an international conference on the issue. "If the problem was two on a scale of one to 10, now it's nine. I'm proposing to the world that we players should all get together and start a new dialogue. There needs to be trust." Zardari arrived in London on Sunday morning from Dubai on a private visit. He was received at the Heathrow Airport by Pakistan High Commissioner to the UK Wajid Shamsul Hasan and senior Chancery officials. Meanwhile, talking to The Sunday Times, Pakistan's High Commissioner to the UK Wajid Shamsul Hasan warned that American raids on Taliban and Al-Qaeda targets in Pakistan could provoke terror attacks in London. The US bombings had killed hundreds of civilians but had failed to eliminate any Al-Qaeda leader, he added. "This will infuriate Muslims in this country and make the streets of London less safe," he said. "There are one million Pakistanis in the diaspora here and resentment is mounting. I'm being flooded by text messages from community leaders saying we must organise our anger. "The Americans' trigger-happy actions will radicalise young Muslims. They're playing into the hands of the very militants we're supposed to be fighting." His remarks followed outrage in Pakistan over five attacks in the past 10 days, including a ground assault in the village of Angoor Adda in which 20 people were killed. US officials claim all were Al-Qaeda supporters but Pakistan insists they were civilians, including women and children. During his London visit, President Zardari will hold crisis talks with British Prime Minister Gordon Brown and Foreign Secretary David Miliband. He will appeal to them to exert their influence to halt the unauthorised bombings. "We hope they will help convince the Americans to stop it, to give space to our fledgling democracy and revive our economy," Wajid said. "Otherwise the army will take over. Is that what they want?" "What have they gained out of this except animosity?" asked Wajid. "They have not killed or captured any prominent Al-Qaeda leader, but the collateral damage is responsible for hundreds of deaths and the reaction is being felt everywhere in the country. "They're playing into the hands of the people we're supposed to be fighting." He insisted that Pakistan had responded to US demands for more aggressive action in the tribal areas and accused the US of jeopardising Pakistan's hard-won new democracy. "It seems no coincidence they do all this just as Zardari takes over. The Americans talk of wanting democracy in Iraq and Afghanistan yet here they have always supported military dictatorships. They must give us space." The British voiced concerns that "killing groups of civilians and not killing high-level targets can only make the situation worse", according to an official. Sensing division between Whitehall and Washington over the new policy, Pakistan's government has decided it will appeal to Britain. Zardari told The Sunday Times last month that he felt Pakistan was being blamed for Nato's failure in Afghanistan. "Okay, we're really bad and done everything wrong this side of the border, but has Nato been able to control the situation with all its soldiers or come up with a proper Afghan army as yet?" he asked. "I'm not pointing fingers, just saying we've all come short of expectations." Zardari will discuss the conflict with Taliban and Al-Qaeda militants in the northern tribal areas with British leaders this week, officials said Sunday. Zardari will meet Gordon Brown on Tuesday (tomorrow) though he is on a private visit for his daughter's admission to university. "It is a private visit but the President will meet the British Prime Minister," Foreign Ministry spokesman Mohammad Sadiq told AFP. Zardari will return to Pakistan on Thursday to address the joint sitting of Parliament and will fly to New York on September 24 to attend the United Nations General Assembly session, the official said.
