In Mexico, two radio journalists have been murdered in the past week. On Wednesday, environmental activist and community radio producer Samir Flores Soberanes was killed in the state of Morelos shortly before a referendum on a thermoelectric plant and pipeline project that he had opposed. On Saturday, radio announcer Reynaldo López was fatally attacked by armed gunmen in Sonora. Another reporter, Carlos Cota, was with López but survived the attack. Four radio hosts have now been murdered in Mexico since the start of the year.
