Provincial police squads of Iran\'s Law Enforcement forces discovered and seized a total volume of almost one ton of different types of narcotics in several operations in the Southern Fars province during the last 10 days, a provincial police chief announced on Saturday. Fars province\'s Police Chief Sirous Sajjadian said that his forces have disbanded 5 drug rings as a result of a series of intelligence operations during the last 10 days throughout the province. He added that police have seized 748kg of opium, 167kg of hashish 33kg of heroin from the disbanded rings. The commander said that his troops have also arrested 55 drug-traffickers and dealers during the said period. Iran, located at the crossroad of international drug smuggling from Afghanistan to Europe, has taken new security measures in its border provinces following several attacks by terrorists and drug traffickers at its Eastern and Western borders. The Iranian police measures along the Eastern borders have forced drug-traffickers to resort to other routes, including the Sea of Oman and the Persian Gulf, for smuggling their drug cargos which originate in Afghanistan and Pakistan. According to the statistical figures released by the UN, Iran ranks first among the world countries in preventing entry of drugs and decreasing demand for narcotics.
