International inspectors have received "credible allegations" that Syria is still using chemical weapons, the White House said Wednesday, Reuters reported. The Syrian government of Bashar al-Assad had pledged to surrender its chemical weapons stockpiles after it launched sarin gas attacks that killed hundreds of people in a Damascus suburb, but international inspectors have found traces of the deadly nerve gas at one of Syria's previously undisclosed military research site. "We're aware that the [Organization for the Prohibition of Chemical Weapons] continues to receive credible allegations that the use of chemical weapons in Syria is still taking place," White House spokesman Josh Earnest told reporters in a briefing.
