On 18 December 2015 the UN Security Council adopted Resolution 2254 on the situation in Syria. Resolution 2254 endorses the efforts of the International Syria Support Group (ISSG) to facilitate a political solution to the conflict under the supervision of the UN, including working towards a nationwide ceasefire and the holding of free and fair elections within 18 months. The resolution also recalls that “the primary responsibility to protect its population lies with the Syrian authorities.”
