LAHORE As the Obama administration, using back-channel diplomacy, is pressing Pakistan hard to get key al Qaeda operatives detained during a successful raid in the suburb of Quetta the other day, Islamabad has ruled out the possibility of handing over the most wanted men to the American or NATO forces. 'This is out of question, a senior intelligence officer said, when asked whether Pakistan would hand over the big fish to the Americans. During background discussion, the officer speaking on the condition of anonymity because he was not authorised to discuss sensitive security matters told this reporter on Wednesday that Islamabad through media reports had come to know that the Americans wanted to grill the arrested suspects. When asked whether Islamabad would allow US investigators to grill the arrested al Qaeda operatives, the officer said: 'the authorities at highest level will consider their (Americans) request once they formally contact the concerned power corridors. However, sources in the Foreign Ministry said that the CIA operatives are likely to be allowed to interrogate the arrested al Qaeda members. 'Both the countries have developed a proper intelligence sharing formula to counter global terror and joint investigations could be more fruitful as far as security of both the States is concerned, he added. On Monday, Pak Army announced that the Inter-Services Intelligence (ISI) and Frontier Corps arrested Younis al-Mauritani, blamed for planning and executing international operations for al Qaeda. Al-Mauritani was nabbed alongwith two other senior operatives of al-Qaeda Abdul Ghaffar al-Shami (Bachar Chama) and Messara al-Shami (Mujahid Amino), according to the Pak Army. Terrorists struck the home of a top paramilitary official and killed at least 23 people including security personnel in Quetta just two days after Pakistan announced the arrests of key al-Qaeda members. Security experts say the twin suicide bomb attack on Wednesday is linked to the recent arrest of three top Al-Qaeda operatives. Officers of Balochistans Frontier Corps took part in the arrests. It was also reliably learnt that the US has stepped up diplomatic pressure on Pakistan to get access to the arrested al Qaeda men. The sources claimed that a top US official from Washington is likely to visit Pakistan next week to hold talks with high-ups in Islamabad. The arrest of Younis al-Mauritani dealt a fresh blow to the al Qaeda just two weeks after the death of al Qaedas No.2 in an apparent drone strike. There is no denying the fact that US needs Pakistans cooperation and assistance to fight the menace of terrorism in Afghanistan and in FATA (Pakistan). Unfortunately events in the recent past including OBL killing by US Marines in Abbottabad, Raymond Davis case, Mehran Base attack and murder of Syed Saleem Shehzad has led to create trust deficit between the officials of both the countries. US had adopted some what coercive tactics to put pressure and get cooperation from Pakistan. This has to be changed through better diplomacy and playing our cards in a more impressive manner. 'When US needs us, we should offer cooperation with dignity, a defence expert commented. The White House believes that Pakistan continues to be an important US partner in the fight against al Qaeda and the relationship between the two countries may not be perfect but it is vital to security efforts in the region. Defence experts say that US must understand geo-strategic realities as related to war on terrorism. 'Diplomacy and policy of tolerance must be followed by both Pakistan and US to continue their efforts to fight the menace of terrorism. Blame game has to end as it does not carry forward the spirit of cooperation essentially needed to eliminate terrorism. The US must realise the sacrifices made by Pakistani people and its security forces in their war against terrorism and assist Pakistan to gain more success, analysts maintained.
