WASHINGTON, Jan. 25 (UPI) -- U.S. Gen. David Petraeus Tuesday wrote a letter to troops in Afghanistan, telling them hard work will continue the "impressive" progress in the war.
Petraeus, commander of the International Security Assistance Force, said U.S. service members and their Afghan counterparts "did tremendous work in 2010" toward furthering the goal of denying al-Qaida safe haven, the Defense Department said.
