At least seven youths and three police were trampled to death Friday during a police raid on a nightclub in Mexico City, security officials said. Police entered the New Divine nightclub to break up the illegal sale of alcohol to minors and a stampede ensued, according to Joel Ortega, a local security official. "Unfortunately, the person in charge of the nightclub took the microphone and announced a police operation was underway," Ortega said, adding that people panicked and rushed to get out, causing a stampede.
