ISLAMABAD, Pakistan (CNN) -- A Taliban spokesman and leader were arrested in Pakistan's volatile Swat Valley, a military official said.
Muslim Khan, a spokesman for the Taliban in Swat Valley, and Mahmood Khan, a Taliban commander in the area, were arrested by security forces, said Pakistan military spokesman Maj. Gen. Athar Abbas.
Three other militants were arrested in the operation in northwestern Pakistan, Abbas said.
Pakistani and U.S. officials believe the group's leader, Baitullah Mehsud, was killed in an August 5 drone attack in Waziristan. A new leader was named afterward.
