On Monday, Finnish, Swedish and Turkish officials met in Brussels to discuss Turkey's security concerns regarding the Nordic countries' Nato membership bids.
Ankara has accused Sweden and Finland of harbouring suspected members of the Kurdish militant group PKK. Turkish officials have also condemned the countries' past decisions to ban arms exports to Turkey due to its involvement in the Syrian war.
The Nato-chaired talks aimed to resolve Turkish opposition to Finland and Sweden joining the military alliance.
Foreign Minister Pekka Haavisto (Green) said in a Monday press conference following the meeting that the two Nordic countries’ terrorism legislation had been brought into question by Turkey. Finland will attempt to prove that Finnish legislation fulfils the criteria other Nato countries follow in this respect, Haavisto said.

While the day's discussions made clear headway on some issues, there is still a long way to go to reach agreement on others, President Sauli Niinistö's office said on Monday.
