The Swedish authorities act as "modern barbarians" by authorizing an action with burning a copy of the Koran near the Turkish embassy in Stockholm, Turkish presidential spokesman Ibrahim Kalin said.

"Sanctioning this action, despite all our warnings, encourages hate crimes and Islamophobia. The attack on sacred values is not freedom, but modern barbarism," he wrote on Twitter.

He added that the Turkish authorities strongly condemn the actions of the Swedish authorities.
