Angry Iranians attacked several gas stations in protest after the government suddenly began long-threatened fuel rationing, while many others rushed to fill their tanks. The Oil Ministry announced the start of rationing Tuesday night only three hours before it was due to begin at midnight. The sudden announcement sparked long lines at stations as Iranians tried to get one last fill-up before the limitations kicked in. Several stations were attacked "by vandals," state radio reported early Wednesday. It did not say how many stations were damaged or give details. The Iranian government had been planning for weeks to implement rationing, which was supposed to begin May 21 but was repeatedly put off. In May, the government reduced subsidies for gas, causing a 25 percent jump in the price.
