Iran's morality police are cracking down on the sale of Barbie dolls to protect the public from what they see as pernicious western culture eroding Islamic values, shopkeepers said on Monday, January 16.

As the West imposes the toughest ever sanctions on Iran and tensions rise over its nuclear program, inside the country the Barbie ban is part of what the government calls a "soft war" against decadent cultural influences.

"About three weeks ago they (the morality police) came to our shop, asking us to remove all the Barbies," said a shopkeeper in a toy shop in northern Tehran.

Iran's religious rulers first declared Barbie, made by U.S. company Mattel Inc, un-Islamic in 1996, citing its "destructive cultural and social consequences." Despite the ban, the doll has until recently been openly on sale in Tehran shops.

The new order, issued around three weeks ago, forced shopkeepers to hide the leggy, busty blonde behind other toys as a way of meeting popular demand for the dolls while avoiding being closed down by the police. A range of officially approved dolls launched in 2002 to counter demand for Barbie have not proven successful, according to Reuters.

Iran has fought a running battle to purge pervasive western culture from the country since its Islamic revolution overthrew a western-backed king in 1979, enforcing Islamic dress codes, banning Western music and foreign satellite television.

As another swipe at the West, Iranians will soon be able to buy toy versions of the U.S. spy drone that it captured in December, Iranian media reported.
