FILE - In this Jan. 16, 2014 file photo, OPCW (Organization for the Prohibition of Chemical Weapons) Director-General Ahmet Uzumcu talks during a press conference, in Rome. With about 92 percent of the world’s declared chemical weapons destroyed, the watchdog overseeing the elimination of poison gas and nerve agents is looking at how to counter emerging threats while still dealing with unfinished business in Syria. The OPCW is marking the anniversary of the entry into force of the Chemical Weapons Convention with a conference focusing on chemical security in a future in which extremists and criminals seem more likely than nations to launch attacks.
