UNITED NATIONS, Jumada II 3, 1435, Apr 3, 2014, SPA -- Syria has packed 40 percent of its chemical weapons arsenal into containers to be taken outside the country and destroyed, and convoy security has been deployed to deal with violence around the port city of Latakia, the head of the mission overseeing the operation said on Thursday, Reuters reported. Syria's U.N. envoy warned that the government may be forced to delay its transports due to the security situation and might miss another deadline for moving the ingredients of its poison gas program out of the country. Sigrid Kaag, head of the joint mission of the United Nations and the Organization for the Prohibition of Chemical Weapons, told the U.N. Security Council the toxins had been loaded into 72 containers at three different sites, said council diplomats who attended the meeting, speaking on condition of anonymity. Once those 72 containers are shipped out of war-torn Syria, some 90 percent of the country's declared chemical weapons stockpile will have been removed for destruction, Kaag told a closed-door council briefing via video link from Damascus. The United Nations said on Thursday that since March 20, no chemicals had been transported to Latakia, where they are to be shipped out of the country for destruction. So far almost 54 percent of Syria's declared chemicals have been removed. Kaag told the Security Council that the Syrian authorities had assigned forces to provide security for the convoys to deal with the increased violence in the Latakia area, diplomats said. -- SPA 22:50 LOCAL TIME 19:50 GMT www.spa.gov.sa/1217023
