15 people killed in latest Mexican massacre

MEXICO CITY - Gunmen killed 15 people at a car wash on Wednesday in a Mexican Pacific coast state where drug-gang violence has risen this year. It was the third massacre in Mexico in less than a week.

The gunmen in three vehicles drove up to the car wash in the city of Tepic and opened fire without provocation, said Fernando Carvajal, public safety secretary of Nayarit state, where the city is located. Fifteen men were killed and three people were injured.

The motive was not immediately clear, but investigators suspect it was the work of organized crime, Carvajal told reporters.
