The Mexican navy says 32 bodies have been discovered in the eastern state of Veracruz, where dozens of bodies were dumped on a road in broad daylight just last month.
The bodies were found Thursday in three houses in the Gulf coast seaport, which has become the latest focal point of the country's brutally violent drug war.
Authorities suspect the violent Zetas drug cartel is responsible for last month's discovery of 35 bodies that were found littered on a main avenue in Veracruz.
President Felipe Calderon has deployed federal police and security forces to Veracruz.
More than 40,000 people have been killed in Mexico since Mr. Calderon launched a military crackdown on illegal drug activity in 2006.
