Gunmen have shot dead at least 10 people in a beer distribution centre near the Mexican city of Monterrey and then stole from the bodies.
Seven people died at the scene. They were found naked or half-naked. Another three people died on their way to hospital.
The attack took place in the municipality of Garcia.
Authorities say they are investigating links to organised crime, possible involving drugs cartels.
Mexico's El Universal newspaper said (in Spanish) that the attack happened in a centre that distributed Corona brand beer to shops in Garcia, 40km (25 miles) from the city of Monterrey.
