Three suspected employees of Mexico’s Los Zetas drug cartel were arrested in the eastern province of Zacapa after a gunfight with security forces, the Guatemalan interior minister said Thursday.

The clash Wednesday in the town of Gualan resulted in no casualties, Mauricio Lopez told reporters in the capital.

He identified the suspects as Vicente Enrique Estrada, 21, Salvador Vargas, 31, and Luis Orlando Vargas, 35, and said all three are Guatemalan citizens.
