Tonight the immigrant population in Stockholm's suburb of Rinkeby was awakened by riots. Around 200 people took part in throwing stones at the police; cars were set on fire and shoots were fired.
Police received the first alarm shortly before 11pm on Wednesday night. A car had been set on fire. When police arrived to the area, they were met by stone-throwers, prompting them to retreat and wait for reinforcements in order to go back into the war-like zone again. The police do not know what caused the unrest.
