Authorities in the northern Mexican state of Sonora say drug cartel groups are behind a string of murders in a disputed corridor along the U.S. border.
At least 11 people have been killed since Friday around the town of Sonoyta, which borders Arizona.
State Public Security Secretary Ernesto Munro Palacios said Wednesday that the gangs are trying to control the area to run drugs into the United States.

The groups are believed to be affiliated with the Sinaloa cartel. Most of the dead have been identified as coming from the state of Sinaloa, which borders Sonora to the south.
