The Mexican army on Friday announced that it has made the largest seizure of drug-cartel weapons in Mexico's history, Associated Press reported. The cache of 540 rifles, 165 grenades, 500,000 rounds of ammunition and 14 sticks of TNT were seized on Thursday at a house in the city of Reynosa, across the border from McAllen, Texas, Mexican Assistant Attorney General Marisela Morales said. «The seizure ... is the largest in the history of Mexico involving organized crime,» Morales told reporters at Defense Department headquarters, where the army displayed hundreds of rifles, pistols, and shotguns, and laid out rows of grenades and crates of ammunition. Morales said the largest previous bust involved a cache of 280 weapons found in 1984. Soldiers detected the cache when they chased suspects into the home after the men refused orders to stop, Morales said. Three suspects were detained.
