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.

Schools and businesses in Culiacan, the state capital of Sinaloa, have shut down and upcoming festivities around Mexican Independence have been canceled as fears over clashes between factions of the Sinaloa cartel disrupt life in the northern city of 1 million.

Authorities in the western Mexican state of Sinaloa on Thursday canceled national day celebrations and shut schools on the back of escalating violence stemming from internal Sinaloa Cartel fighting, which has left 12 people dead since Monday.
