CIUDAD JUAREZ, Mexico (Reuters) -A Mexican photojournalist was killed in Ciudad Juarez in the early hours on Thursday while working as a ride-share driver, authorities and his employer said. Ismael Villagomez, a photographer for newspaper El Heraldo de Juarez, was shot and killed in his vehicle in the notoriously violent border city around 1:30 a.m., according to local authorities. Mexico is one of the most dangerous peace-time nations in the world for journalists, although investigators said they had not been able to immediately establish whether his killing was related to his profession.
