In Mexico, two activists who advocated for the rights of farmers have been found shot to death in the southwestern state of Guerrero. The murdered activists were members of the Emiliano Zapata Revolutionary Agrarian League. A group leader said a third member is missing. The killings are the latest in a spate targeting journalists and activists in Mexico. Other victims include an environmentalist murdered in Veracruz last week and an indigenous rights activist killed last month in Oaxaca.
