From the UK, more fodder for the debate over the US drone assassination campaign and the acceptability of killing citizens: In early February, a leaked white paper from the Obama Justice Department caused a small stir, because it laid out an expansive set of circumstances under which the president could order a citizen killed abroad. In September 2011, the US killed Al Qaeda propagandist Anwar al-Awlaki and Samir Khan, both US citizens, and a few weeks later a US drone strike in Yemen also killed Awlaki's 16-year-old son, Abdulrahman.
