WASHINGTON - Pakistan has told the Obama administration to reduce the number of US troops in the country and has moved to close three military intelligence liaison centres, The Los Angeles Times reported Friday, citing unnamed US officials. The move reflects a clear sign of Pakistans deepening mistrust of the United States, as US Secretary of State Hillary Clinton began a visit to Islamabad in bid to mend the strained Washington-Islamabad ties. The liaison centres, also known as intelligence fusion cells, in Quetta and Peshawar are the main conduits for the United States to share satellite imagery, target data and other intelligence with Pakistani ground forces conducting operations against militants, including Taliban fighters who slip into Afghanistan, the newspaper said. US special operations units have relied on the three facilities, two in Peshawar and one in Quetta, to help coordinate operations on both sides of the border, the LA Times said, quoting US officials. The US units are now being withdrawn from all three sites, the officials said, and the centres are being shut down. The decision has not affected the CIAs ability to launch missiles from drone aircraft in northwest Pakistan, the paper said. The dispatch said it wasnt immediately clear whether the steps are permanent. The closures, which have not been publicly announced, remove US advisers from the front lines of the war against militant groups. Earlier, the US military said on Wednesday it has begun pulling some American troops out of Pakistan after Islamabad requested a smaller presence, amid tensions over a US raid against Osama bin Laden. The Pakistani government had asked for a scaling back of the US contingent of more than 200 troops earlier this month, Pentagon spokesman Colonel Dave Lapan said. We were recently (within the past 2 weeks) notified in writing that the government of Pakistan wished for the US to reduce its footprint in Pakistan. Accordingly, we have begun those reductions, Lapan said in a statement. He did not say how many troops would be pulled out. Most of the US personnel are special forces that train and advise Pakistani troops. The withdrawal of some US troops underscored the crisis between the two countries in the aftermath of the US raid that killed Osama bin Laden on May 2, despite US diplomatic efforts to smooth over tensions. Even before the operation, Pakistani officials had told the Americans they wanted about 20 to 30 of the roughly 150 special forces troops to be withdrawn after a CIA employee shot and killed two Pakistanis in Lahore.
