A U.S. drone strike killed two people in Yemen on Saturday. According to the Associated Press, the United States has now carried out nine drone strikes there in two weeks, killing 38 people. McClatchy says the surge has marked the most concentrated series of drone strikes in Yemen in more than a decade. While Yemeni officials say the dead are suspected militants, many have not been identified. A senior Yemeni official told CNN the number of strikes is actually 12 and that nearly a dozen of those killed are believed to have been innocent. Yemeni activist Farea al-Muslimi tweeted the names of three civilians he said were injured in Saturday’s attack in the south of Yemen.
