In Iraq, the prices of small arms have increased since the U.S. invasion. According to a report by the New York Times, Kalashnikovs were priced between $75 to $150 in early 2003. By late 2006, the prices increased to the range of $210 to $650. In some areas of Iraq, the price has increased to $800, with compact Kalashnikovs favored by Osama bin Laden selling for as much as $2000.
