A Pakistani family whose account of a U.S. drone strike in North Waziristan was cited last week in Amnesty International's report on the covert program arrived in Washington on Tuesday, intent on putting a human face on the number of civilian casualties (AFP).  According to Nabila Rehman, she was picking okra with her family in their garden last October when a drone strike killed her grandmother and injured seven other people; the U.S. government has never officially acknowledged the strike.  The Rehmans, who will appear at a press conference with U.S. Congressman Alan Grayson (D-FL) on Tuesday, are also featured in a new documentary by the Brave New Foundation called "Unmanned: America's Drone Wars."
