Last May, photographer Lorenzo Tugnoli, on assignment for The Washington Post, visited Yemen, reporting on the humanitarian crisis resulting from the ongoing political conflict and the Saudi-led airstrikes that have rocked the country over the last few months and years. His work forms part of this year’s Visa pour l’Image photojournalism festival in Perpignan, France. In the following text, Tugnoli reflects on the contrasting aspects of Yemen’s two major cities, Aden and Sanaa, which have found themselves at the center of the current political and humanitarian crises.
