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 the eastern state of Veracruz.

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

But uncertainty remains over whether this crackdown will make gangs more fearful of the police.
