BANGUI, May 2,2018 (MENA) - A priest was among at least 16 people killed as new sectarian violence targeted a church, mosques and health facilities in Central African Republic's capital, an aid group, hospital and the United Nations said, The Washington Post reported. Medecins Sans Frontieres, which reported six dead, called for calm after some Bangui residents threatened the SICA hospital, where some of the more than 50 people shot and wounded were being treated. Medical workers have a duty to treat people "regardless of their background, religious or political affiliations," said Anne-Marie Boyeldieu, MSF's head of mission in Central African Republic. Anger has been high among some in the capital since UN peacekeeping mission and local security forces launched a joint operation in the largely Muslim neighbourhood of PK5 in early April to arrest members of armed criminal groups after their leaders refused to disarm. The dead bodies of 17 civilians were laid in front of the UN peacekeeping offices shortly afterwards. Tuesday's violence erupted in the PK5 and Fatima neighborhoods, MSF said.
