Two men and one woman were killed when unidentified assailants opened fire outside city hall in Sonora in northern Mexico. Sonora has been the scene of bloody turf battles between several cartels, but it was unclear if Thursday’s shooting was related to that.
The shooting comes one day after state authorities said they found 14 clandestine graves near Miguel Aleman, a town north of Guaymas. State prosecutors say the burial pits contained bones, some burned, and decomposing bodies, but said they cannot yet determine the number of victims.
Sonora has been the scene of drug gang turf battles thought to involve factions of the Sinaloa Cartel, allies of the Jalisco cartel and a gang allied with fugitive drug lord Rafael Caro Quintero.
Residents are urged to stay away from the downtown area in the Gulf of California port of Guaymas.
