Air traffic has resumed at Sweden's second largest airport after being suspended for several hours as bomb technicians investigated a suspicious bag that turned out to be harmless, according to AP. All incoming and outgoing flights were halted in the afternoon Sunday after police said a bag with suspected dangerous content was discovered in the security check at the international terminal. The terminal was evacuated. Airport officials said in a statement later Sunday that the content was identified as harmless and that the airport had reopened to traffic. Earlier in the day, airport operator Swedavia's spokesman Jan Lindqvist said about 2,000 passengers were affected.
