The 2013 Nobel Peace Prize was awarded to the Organisation for the Prohibition of Chemical Weapons, for their "extensive work to eliminate chemical weapons". The award citation indicated the organization was awarded the prize, because they “have defined the use of chemical weapons as taboo under international law. Recent events in Syria, where chemical weapons have again been put to use, have underlined the need to enhance the efforts to do away with such weapons.” The committee criticized Russia and the United States for not meeting the extended deadline for destruction of its chemical weapons, and noted that certain countries "are still not members". The OPCW was the 22nd organization to be awarded the prize.
