The heads of several UN humanitarian agencies issued a joint statement calling for an end to the conflict in Syria and for urgent action to enable humanitarian access. They noted that after four years of conflict, over 9 million people now require assistance, with many areas under siege and civilians subjected to indiscriminate attacks. While humanitarian agencies are doing all they can, the situation requires those engaged in the conflict and those with influence over them to take action by lifting sieges, ending attacks, and allowing unconditional access to all people in need. The statement calls on parties to take urgent action to enable access and end violations of international law.
