'Iran's eastern border secured'
A senior Iranian police commander says most parts of the country's eastern border have been secured against drug-trafficking, Press TV reported.
"The only issue is the cordoning of the southern part of Sistan-Baluchestan Province," IRIB quoted Hamid-Reza Hossein-Abadi, the commander of the Iranian police narcotics squad, as saying on Monday.
He also said that efforts were being made to fully secure all the eastern borders of the country to the Sea of Oman.
Hossein-Abadi stated that the government has been allocating funds toward that end.
On different occasions, Iranian officials have said that the US and Britain are playing a major role in Afghanistan's lucrative drug trade.
They have criticized Western countries over their policies toward Iran's eastern neighbor, where poppy cultivation has drastically increased since the US-led military occupation of the country began in 2001.
Some 13,000 tons of drug catalysts are brought into Afghanistan every year as the country produces some 90 percent of the world's opium.
Iranian police officials maintain that drug production in Afghanistan has had a 40-fold increase since the war and occupation began.
