Mexican army soldiers seized more than 300,000 liters (79,000 gallons) of drug precursors in the Gulf coast state of Veracruz and arrested 13 people in an operation against drug trafficking and organized crime, the Defense Secretariat said.

In a statement, the secretariat said the operation took place Wednesday in a building located in the municipality of Coatzacoalcos, south of Veracruz, "in response to a citizen's tip."

It added that "chemical products were being moved in an illicit manner" at the site of the raid.

The military confiscated 289,200 liters (76,000 gallons) of a substance with the characteristics of xylene, and 43,200 liters (11,400 gallons) of a composition that appeared to be butyl cellosolve. Each of the products has several commercial applications.

Also seized were 198 containers capable of holding 1,000 liters (264 gallons) of liquid, seven truck tractors and two truck-tractor transmissions. EFE
