The Pakistani government says since 2008 only three percent of casualties from U.S drone strikes have been civilians.
The percentage is surprisingly low considering recent estimates from independent organizations.
The Bureau of Investigative Journalism, based in London, has estimated that at least 300 civilians have been killed by drones in Pakistan since 2008.
The Washington-based New America Foundation put the figure at 185 civilians. These estimates are often compiled based on media reports about the attacks.
A new Pakistani governmental review claims, however, only 62 innocent people have been killed.
The Pakistani government has publicly criticized U.S. drone attacks, though it is known to have secretly supported at least one strike in the past.
