WASHINGTON-In a significant shift, the US military is assisting the Pakistani Army in its offensive on militants in South Waziristan by providing valuable surveillance video and intelligence gleaned from CIA-operated unmanned aircraft, according to a report in The Los Angeles Times. The assistance the first time Islamabad has accepted such help includes images from armed Predator drones gathering intelligence for the sole purpose of aiding the Pakistani offensive, Defence officials told the newspaper. The move marked the deepest American involvement yet in a Pakistani military campaign, it said. Providing the information, while helpful to the Pakistanis, also shows how the Obama administration intends to put pressure on terrorists operating in the region as the White House overhauls its strategy for Afghanistan, officials said. Recent attacks on Pakistan have shaken the govt, likely swaying officials to accept American help in striking the militant stronghold, LA Times said. 'We are coordinating with the Pakistanis, the paper quoted an unnamed senior US military official as saying. 'And we do provide Predator support when requested. American assistance is considered controversial in Pakistan, which wants to avoid appearing dependent on the US government or military, the newspaper noted. However, a Pakistani military official confirmed to the Times that the US was helping provide a 'composite picture of the enemy. The Pakistani official and a senior US official both said that the offensive followed high-level talks between the two nations military leaders. Gen. Stanley McChrystal, the top US and NATO commander in Afghanistan, had flown to Islamabad to work out coordination on the border and intelligence-sharing issues before the Pakistani military campaign began, the Pakistani official said. Similarly, Pakistani officers, including the commander of the nations air force, have held meetings with Admiral Michael Mullen, Chairman of the Joint Chiefs of Staff, and other US officials in Washington in recent weeks. White House deliberations over McChrystals recommendation to send reportedly 40,000 more troops to Afghanistan have received heavy attention in recent weeks, but the Obama administration also has examined how to provide more effective assistance to Pakistan. In the last 18 months, US drone missile strikes have killed at least 13 senior al-Qaeda or Taliban fighters in Pakistans tribal region.
