Turkey has reservations over the prospect of Finland and Sweden's entry to the North Atlantic Treaty Organizations, NATO.

Foreign ministers of the alliance are meeting on Saturday and Sunday in Berlin.

Finnish and Swedish foreign ministers also took part in the talks on Saturday. Finland made clear that it wants to join the alliance and Sweden is also considering joining.

NATO Deputy Secretary General Mircea Geoana said that the two ministers briefed the alliance members about their situation of national security and possible NATO membership.

Czech and Norwegian foreign ministers told reporters before the meeting that their countries support the NATO entry by Finland and Sweden.

But Turkish foreign minister Mevlut Cavusoglu pointed out that majority of the people of his country oppose the membership of Finland and Sweden which he says support terrorist organizations. He was referring to their support of Kurdish militant groups that Turkey has designated as terrorist organizations.

Cavusoglu, however, is willing to discuss the matter with his counterparts.

To join the NATO, the unanimous support of the members is needed. Finnish foreign minister Pekka Haavisto expressed confidence in his country's successful bid to the membership but stressed the importance of good communication since any member can block new entrants.
