At least 16 people were left dead in two massacres in the Mexican states of Michoacan and Guerrero.
A statement from the Michoacan state prosecutors’ office said nine burned bodies were found inside an SUV in the municipality of Cuitzeo in an area with pipelines run by state oil company Petroleos Mexicanos.
Prosecutors said there were signs of the possible clandestine tapping of the pipelines and authorities are looking into whether the deaths are related to fuel theft.
Also on Saturday, state prosecutors in Guerrero said seven people, including two children, were shot to death in neighbouring houses near Tepecoacuilco de Trujano, a municipality 15km from Iguala, the city where 43 students disappeared in 2014.
Local media reported the seven dead were members of the same family.
