The joint inquiry into toxic gas attacks in Syria was extended to the end of October following a request from the investigators.
A team from the United Nations and the Organization for the Prohibition of Chemical Weapons has been investigating the attacks for some 12 months.
Syria agreed to destroy its chemical weapons in 2013 under a deal brokered by Moscow and Washington. According to Reuters in Sep 2016, the team's initial inquiry revealed that Syrian government troops attacked twice with toxic gas and Islamic State militants used sulfur mustard gas.
The UN Security Council (UNSC) authorized the extension. UN chief Ban Ki-moon has asked the UNSC to make sure the guilty are punished.
