MUZAFFARABAD - The Army on Sunday took control of banned Lashkar-e-Taiba's central office and arrested its several key commanders during an operation in an area of Pakistan Occupied Kashmir, sources said. A helicopter was also reportedly used in the action, which was supervised by a Brigadier, source added. But the civil administration did not confirm the incident. Sources said that the Army faced stiff resistance and there was also exchange of fire during the operation, which was launched to seize control of the LT central office, situated at Shawai Nullah. A chopper was also seen hovering over the area and it also fired on the target, they added. They further said that the soldiers had cordoned off the entire area and no one was being allowed to go there. Ambulances also rushed to the site of the incident but it could not be ascertained as to how many people were killed or wounded in the operation, they added. Sources stated that the Army took control of LT's central office and captured 20 of its members, including several important commanders while many others succeed to flee. When contacted to confirm the military action, the Deputy Commissioner of Muzaffarabad said that the district administration had neither any knowledge of this nor could give any information in this regard. Maqbool Malik from Islamabad adds:An ISPR spokesman when contacted by TheNation, said, "If any such event, which is to be dealt with by the Interior Ministry, you should better get in touch with the concerned ministry in this regard." When contacted, Interior Advisor Rahman Malik was unable to either confirm or deny the report in the first place. "So far I am not aware of the actual occurrence, probably it was action by the local police, let me check it out and then I shall be able to say anything on that," he promised. However, The Nation's frequent efforts to get in touch with Malik could not prove fruitful till the filing of this report as his staff attending the phone kept on saying that he would be available soon. Agencies add: Islamabad on Sunday denied reports it has agreed to a 48-hour timetable to take action against Pakistanis accused of involvement in the Mumbai attacks. The Washington Post reported that Pakistan had agreed to a deadline imposed by the United States and India to arrest three people and formulate a plan to take action against a militant group accused of involvement in the attacks. The US daily quoted an unnamed Pakistani official saying India had asked Pakistan to hand over a leader of the group, Lashkar-e-Taiba, as well as a former director of Pakistan's Inter-Services Intelligence (ISI) agency. Some Indian papers allege the powerful spy agency trained the attackers. But Pakistan's foreign office on Sunday denied any such deadline had been set. "There is no deadline, India has not set any deadline, this is all rubbish," foreign office spokesman Mohammad Sadiq told AFP. According to the Post, Pakistan has agreed to a 48-hour timetable set by India and the US to formulate a plan to act against Lashker-e-Toiba (LeT) and to arrest at least three Pakistanis who Indian authorities say are linked to the Mumbai terrorist assaults, the Washington Post reported citing a high-ranking Pakistani official. The official, who spoke on the condition of anonymity because of diplomatic sensitivities, said India had also asked Pakistan to arrest and hand over LeT commander Zaki ur-Rehman Lakhwi and the former director of Pakistan's spy agency Inter-Services Intelligence (ISI), Hamid Gul, in connection with the investigation, the Post said Saturday. President Asif Ali Zardari, who has expressed his country's solidarity with India, is expected to review plans by his nation's top military and intelligence officials and follow through on India's demands, the official was quoted as saying. 'The next 48 hours are critical,' the official added. US Secretary of State Condoleezza Rice, the daily said, had urged Pakistan to hand over Yusuf Muzammil, an LeT leader whom Indian and US investigators have identified as the mastermind behind the attacks, and other suspects. The Post cited an unnamed high-level source in the Indian government as saying India had 'clear and incontrovertible proof' that the Pakistan-based LeT planned the attacks and that the group's leaders were trained and supported by ISI. 'We have the names of the handlers. And we know that there is a close relationship between the Lashker and the ISI,' the source told the Post. US intelligence officials, however, were more cautious in their interpretation of the evidence, the US daily said. Although US analysts acknowledged historical ties between Lashkar and ISI as well as more recent contacts between militants and Pakistani intelligence officers, they said they were not convinced that Pakistan supported the attacks in any significant way. 'Even if there were contacts between ISI and LeT, it's not the same as saying there was ISI support,' it quoted an unnamed US counter-terrorism official as saying. The official, the Post said, would not dismiss the possibility that further evidence would reveal active ISI involvement but said: 'The evidence we've seen so far does not get you there.' The Wall Street Journal said Western intelligence officials have been quietly mediating between India and Pakistan. The CIA 'is playing a huge role in this and trying to work behind the scenes and get past the emotion', it said citing a former senior intelligence official. Indian police have a sample of Kasab's DNA that they plan to provide to the FBI, which would check whether he is from the family he claims as his own in Faridkot village, the Journal said. The bureau would need to compare it with the DNA of any family member. The New York Times also cited a senior American counter-terrorism official as saying it was highly likely that local accomplices were involved. 'They couldn't have gotten to the places they did without local help,' the unnamed official cited by the Times said. 'They just moved too quickly. They had to have had more assistance on the ground.'
