Sweden urged to take action by Turkey over flag incident.

Turkey has called on Sweden to prosecute those responsible for projecting the flag of the Kurdistan Workers' Party (PKK) onto the parliament building in Stockholm on the day of Turkish elections. The incident could raise the stakes ahead of a mid-July NATO summit at which some alliance members are urging Turkey to back Sweden's membership bid. Turkey objects to Sweden's bid, saying Stockholm harbours members of militant groups it considers to be terrorists and has not fulfilled its part of last year's deal meant to assuage Ankara's security concerns.
