Iran is planning to construct a wall along its Afghan border in an effort to halt drug trafficking. The deputy head of Iran’s Drug Control Headquarters announced Wednesday that the entire 435-mile border "will be sealed with concrete walls and barbed wire," all slated to be completed by March 2010. Iran wishes to crack down onAfghani drug production, said the official. Iran has been critical of the West’s failure to enact hard-line policies against drug trafficking. The official noted that since the US-led military operation in Afghanistan began in 2001, poppy cultivation has increased dramatically, rather than diminished. "It seems that the West is supporting drug production in Afghanistan rather than fighting against it," he said.
