Diplomats and premium visa-holders in Saudi Arabia told AFP that the conservative kingdom has quietly eased restrictions on purchasing alcohol for select foreign residents.While the government has not made any statements regarding the sale of alcohol in recent days, the sources said non-Muslim individuals with so-called premium resident status are now able to buy booze at the country's sole liquor store in Riyadh, which was previously reserved for diplomats.AFP spoke with four people who said the rules had changed, including two diplomatic sources and a couple of residents with premium visa status.
