A U.S. drone strike has reportedly killed four people traveling in a car in southeastern Yemen. Unnamed local sources identified the victims as al-Qaeda suspects. It was the third such attack to hit Yemen in a week, including last Monday’s strike, which killed a 12-year-old boy. Meanwhile, the latest tally from the Bureau of Investigative Journalism shows U.S. drone strikes have killed nearly 2,500 people since President Obama took office, including more than 300 civilians. Obama has overseen nearly nine times as many strikes in Pakistan, Yemen and Somalia as his predecessor, President George W. Bush.
