(AP) – Doctors Without Borders is warning of a worsening situation in the Yemeni city of Taiz, where hospitals have been repeatedly attacked and where some 200,000 people are facing shortages of food, water and medicine. Djoen Besselink, the head of the aid group’s Yemen mission, told reporters in Jordan on Monday that attacks on hospitals, ambulances and medical staff had severely limited the group’s activities in the city, which has been partially besieged by Houthi rebels since April 2015.
