Attack in Mexican town kills 20, including mayor, officials say

Gunmen allegedly affiliated with a drug gang have killed 20 people, including a mayor, in an attack in the southern Mexican state of Guerrero, local officials said.
According to security officials, gunmen burst into a meeting between the mayor and city officials on Wednesday in the town of San Miguel Totolapan and left the building riddled with bullet holes.
“This act occurred in the context of a dispute between criminal gangs,” Ricardo Mejia, Mexico’s assistant secretary of public safety, said on Thursday.
The town has had a history of disputes between criminal organisations, and Mejia said a group known as the Tequileros have been locked in a dispute with the Familia Michoacana gang.
