The U.S. military is shifting its focus in Afghanistan to target the Taliban rather than al-Qaida, but a shortage of unmanned drone aircraft may hinder the effectiveness of the new mission.

The military has already shifted about eight Predator drones away from scouring remote mountain ranges to focusing on major Taliban strongholds. Los Angeles Times (07/30)
