(UN News Centre) – Citing attacks against aid workers in Syria, the removal of live-saving supplies from convoys and bureaucratic impediments restricting access, the United Nations Emergency Relief Coordinator has called for ensuring immediate and safe humanitarian access to save lives that are dependent on assistance. Briefing the Security Council today, Stephen O’Brien, the Under-Secretary-General for Humanitarian Affairs, also underlined the need for a sustained reduction in fighting to ease the burden on civilians and create an environment conducive for assistance.
