Turkish President Recep Tayyip Erdogan has suggested that Ankara may agree to Finland joining Nato, but not Sweden, the BBC reports.
He criticised Sweden’s refusal to extradite dozens of people allegedly tied to Kurdish militant groups and other critics of his government.
“If you absolutely want to join Nato, you will return these terrorists to us,” said Mr Erdogan.
His comments come days after Turkey suspended talks to accept the two Nordic nations as members.
The move was prompted by a series of controversial protests in Stockholm, including one during which a copy of the Koran was burned.
