This comes as Turkey’s foreign minister says Sweden and Finland must now take "concrete steps" to alleviate his country’s security concerns to overcome Ankara's objections to their NATO membership bid.

Foreign Minister Mevlut Cavusoglu said Friday that delegations from the two Nordic countries have returned home with Turkey's demands after a visit this week and Ankara is awaiting their answers.
