Mexican authorities say their redoubled efforts to stem drug violence in Veracruz is proving to be a success.

They claim they have captured gunmen responsible for killing dozens of people in eastern state of Veracruz.

The police say the suspects are members of the New Generation Gang which is battling for control from the Zetas drug cartel.

But uncertainty remains over whether this crackdown will instill fear in any gangs of law enforcement.
