(UN News Centre) – Witnessing first-hand the “shocking” devastation in Yemen’s main port city of Aden, the top United Nations relief official in the country today declared that the humanitarian consequences of the conflict are “catastrophic,” making an urgent plea for safe, unhindered access for aid workers and a major scale-up of funding. “The intensification of violence and conflict over the past four months have devastated the city and destroyed the lives and livelihoods of the majority of its people. As has become all too familiar in contexts of war, civilians are paying the heaviest price,” the UN Humanitarian Coordinator for Yemen, Johannes van der Klaauw, said in a statement issued by the UN Office for the Coordination of Humanitarian Affairs (OCHA).
