Gunmen killed 11 relatives, including five young girls, in a northern Mexican city plagued by drug cartels while three people from another family were murdered in a second attack.
The two shootings are believed to be related to a dispute between rival gangs in Ciudad Victoria, said Herminio Garza Palacios, secretary general of Tamaulipas state.
Gunmen burst into a home in the Lopez Mateos district this morning, killing two men, four women and five young girls, he said in a video message.
45 minutes later, armed men stormed the other family's home in the Revolucion district, killing a man and two women and wounding four others.
Ciudad Victoria is the capital of Tamaulipas, one of the country's most violent states, where the Gulf and Zetas drug cartels have fought ultra-violent turf wars for years.
