KABUL - Afghan and U.S.-led coalition troops have destroyed drugs worth more than $350 million and three drug laboratories in southern Afghanistan. NATO said Wednesday the narcotics seizure may be the largest ever made in Afghanistan. Acting on intelligence, the troops targeted an area of Baghran district in the southern Helmand province on Monday that was suspected of being a manufacturing site for drugs.

The money from the drugs was believed to be bankrolling attacks on Afghan and coalition forces.

Also destroyed in the sweep was more than 26,000 pounds (12,065 kilograms) of chemicals used to make drugs, 220 pounds (100 kilograms) of heroin and 176 pounds (80 kilograms) of opium.
