The United States Monday condemned the killing of an American in Yemen and urged authorities to hold those accountable after Al-Qaeda claimed responsibility. The State Department confirmed that Joel Shrum was shot Sunday in Taez and that it was working to repatriate his remains. Shrum was an American working for the International Training Development Center, a non-governmental organization. "We condemn this terrorist act in strongest terms, and we express our deepest condolences to his family and his friends," State Department spokeswoman Victoria Nuland told reporters. "We are urging Yemeni authorities to bring to justice those responsible for this heinous crime." A statement attributed to Al-Qaeda affiliates claimed responsibility for the attack.
