Peruvian police said on Wednesday that in their nationwide anti-drug operation last week, they seized 252 kg of cocaine and arrested 278 suspects.
In the operation codenamed "White Mountain," the police also seized 263 kg of coca leaves, large sum of money and some weapons.
They also smashed four drug rings of relatively large scale in capital Lima and the northwestern coastal city of Trujillo, dealing a heavy blow to the rampant underground drug dealings across the country.
Located in the notorous drug-producing "Silver Triangle" in South America, Peru is a world's major cocaine producer, second only to Colombia, producing about 200 tons of cocaine a year. Most of the cocaine is exported illegally and only 10 percent is seized.
Illegal drug producing and trafficking activities inside the country have become increasingly rampant recently, triggering the Peruvian government's heavy-handed crackdowns.
