The United States has escalated its unilateral strikes against al-Qaeda members and fighters operating in Pakistan's tribal areas, partly because of anxieties that Pakistan's new leaders will insist on scaling back military operations in that country, according to U.S. officials.
Washington is worried that pro-Western President Pervez Musharraf, who has generally supported the U.S. strikes, will almost certainly have reduced powers in the months ahead, and so it wants to inflict as much damage as it can to al-Qaeda's network now, the officials said.
Over the past two months, U.S.-controlled Predator aircraft are known to have struck at least three sites used by al-Qaeda operatives. The moves followed a tacit understanding with Musharraf and Army chief Gen. Ashfaq Kiyani that allows U.S. strikes on foreign fighters operating in Pakistan, but not against the Pakistani Taliban, the officials said.
