NEW YORK - President Asif Ali Zardari said Sunday that Pakistan would try Al-Qaeda's top leaders - Osama bin Laden and Ayman al-Zawahiri - in Pakistan if they were captured, but  they could also be turned over to the United States. "(W)e can hand them (bin Laden, al-Zawahiri) over, (or) we can try them. That is the policy which has been followed in the past and that will be pursued in the future also," President Zardari said in a CNN interview when asked if he would hand them over to the United States. "I will go around with my friends and see what they wanted. if they want them tried in Pakistan, we will try them in Pakistan. If they want them tried in New York, so be it," he told CNN's Wolf Blitzer in "Situation Room" news show. Blitzer expressed satisfaction at the "clear" answer given by President Zardari, who was preparing to return to Pakistan after a week-long visit to New York at the head of Pakistan's delegation to the 63rd session of the UN General Assembly. Asked if he knew the whereabouts of Osama bin Laden, he said, "If I did know, he wou-ldn't be there." Responding to other questions, he said the government institutions were united in fighting terrorism and urged the United States to step up intelligence cooperation with Islamabad to pursue any terrorists that might be hiding on the Pakistani side of the Afghan border. He reiterated Pakistan's firm opposition to unilateral action into its territory by Afghanistan-based US forces, saying the Pakistani forces would do the job better. "If there is actionable intelligence of that high priority, share with us, we will do the job." The President said he commanded control over all security and intelligence organisations. "Definitely, absolutely," he said of all government institutions being on the same page as far as the US and the fight against terrorism are concerned. The fight against terrorism, he underscored, was Pakistan's fight. Commenting on US presidential candidate's remarks in election campaigns on the strategy to take out any top Al-Qaeda operatives hiding on the Pakistani side, Zardari argued that the country's forces would do the job better. He pointed out that the candidates favouring unilateral actions qualify their remarks with certain stipulations like if Pakistan was unwilling to go after the authorities. "But in this case the Pakistani authorities and the President of Pakistan is more than willing." Terming unilateral actions into Pakistani territory as counterproductive in the fight against terrorism, President Zardari emphasized the job will be better done by the Pakistani forces. "Let us do the job, we can do a better job than anybody else can. Its partly and mainly our war. We will fight it," he told CNN's Late Edition, referring to all friends of Pakistan who sometimes get "overindulgent" in the border region. Regarding an incident last week about the two Afghanistan-based US helicopters entering Pakistani territory, he said the Pakistani forces fired flares in their direction to caution that they had crossed the Afghan border into Pakistani territory. "I think there was a flare directed at them, not a fire directed at them. the first flare was fired, and they realised that they had crossed over and went back." "I think the open fire is not to get them down, or down helicopters, but it is to warn them that they have crossed over without realising. Most of the time in engagements, they don't even know that they have crossed over the border. There is such a murky border between Afghanistan and Pakistan,  half the hill is here, half the hill is in Afghanistan, so last that I heard of was a flare fired at them , just to warn them that they had crossed over." Asked whether there was any chance of encounter between the US and Pakistani troops he said, "I won't be worried about that. There has always been friendly fire even in your wars, there is friendly fire and sometimes you get your own, so I would not be worried about it, I would be concerned  if something like that happened." The President confirmed that the government had thought of holding a dinner at the Marriott Hotel in Islamabad last weekend at the time when a massive bombing killed more than 50 lives but added the plan was changed three days before. "We got it changed about three days earlier, but you know these guys hunt like wolf packs so obviously the information did not get to them. "We were supposed to have dinner there that night. The Speaker had actually booked the place and asked for the rates, but than we changed our minds  and had it at the prime minister's house where we all were sitting including the prime minister , General (Ashfaq) Kayani, the chief ministers, excluding the chief minister of Punjab, everybody was there. He said there was no prior information about the bombing plot. Zardari said the government was "still investigating, it was too early (to identify the perpetrators), but obviously it is people who do not want democracy to flourish in Pakistan." The president agreed that the Marriott bombing did have the "finger-marks and hallmarks of an Al-Qaeda-affiliated organisation that is very clear." Agencies add: President Zardari denied that the Pakistan Army had been given orders to open "fire" at US helicopters crossing over from Afghanistan into Pakistan's airspace, saying the recent incidents were aimed to "warn them" that they have violated the international border. He maintained that the distrust within American officialdom of Pakistani security and intelligence forces was a thing of the past. He said the Marriott hotel bomb attack was perpetrated "obviously (by) people who don't want democracy in Pakistan." Asked if his speech at the United Nations in which he said Pakistan would not allow "friends" to violate the territorial integrity of Pakistan was a reference to the US, Zardari said, "I am referring to friends who sometimes get overindulgent." To a question, Zardari said he did not know whether Osama bin Laden was hiding with the Taliban in the tribal areas, but vowed to bring him, and other Al-Qaeda leaders, to justice, stating that anybody believing he was on the Pakistani side of the border should share information with the country. "If I did know, he wouldn't be there," he said.
