Some 53 people have been killed and 51 others are missing in Mexico's western Sinaloa state since rival factions of the Sinaloa Cartel began clashing on Sept 9, local authorities said on Friday, with gruesome violence showing no signs of abating.

Mexican President Andrés Manuel López Obrador says the United States is partially responsible for a wave of violence in the state of Sinaloa that has left dozens dead in the past two weeks, with bodies repeatedly found on public streets and highways.

Two warring factions of the Sinaloa cartel have clashed in the state capital of Culiacan in what appears to be a fight for power since two of its leaders were arrested in the United States in late July.

At least 30 people have been killed in the past two weeks in Mexico’s northern state of Sinaloa as two factions of the powerful Sinaloa cartel continue to clash.

Mexican leader says the U.S. bore some responsibility "for having carried out that operation" to arrest Ismael 'El Mayo' Zambada.

Mexican President Andrés Manuel López Obrador is asking the warring factions of the Sinaloa cartel terrorizing the capital city of Culiacán to act "responsibly” so no one else gets killed.
