A U.S. drone strike killed three people in northwest Pakistan earlier today, marking the first such attack since Pakistani Prime Minister Nawaz Sharif publicly called for President Obama to end the strikes last week. The identity of the victims has not been confirmed, but Pakistani intelligence officials say they are suspected militants, as is generally the claim with U.S. drone attacks. The Bureau of Investigative Journalism says at least 400 civilians have been killed by CIA drone strikes in Pakistan since 2004. But in a twist Wednesday, the Pakistani government significantly downgraded its official estimate of civilian casualties. Previous reports have detailed the Pakistani government’s extensive cooperation with drone strikes. Today’s attack came as members of a Pakistani family are in the United States calling for an end to drone strikes which they say are killing innocent people.
