Mexico City - A shoot-out between suspected drug cartel gunmen and police in central Mexico has left at least six people dead. Masked men attacked a police station in the town of Jerécuaro and shot two officers and a secretary dead. They killed another two police officers when they made their getaway. One of the gunmen was killed in the attack. Police say they found hand grenades, weapons and cocaine in three vehicles abandoned by the gunmen. The attack may have been in revenge for recent police operations against drug cartels.
