Mideast Iran Narcotics

In this Sunday, June 1, 2014 photo, an Iranian border guard patrols Iran’s Dogharoun border with Afghanistan, near Taibad in eastern Iran. In the face of Afghanistan’s unprecedented boom in opium production, neighboring Iran is trying to baton down its border to slow down smuggling, building moats, walls and other large-scale projects. Iran spent more than $26 million last year alone on the border projects which also include large embankments, new border posts and lengths of barbed wire along parts of its 2,000-kilometer (1,200-mile) border with Afghanistan and Pakistan.
