Turkey is not blackmailing NATO with its rejection of a defense plan for the Baltics and Poland, and has full veto rights within the alliance, a Turkish security source said on Monday ahead of a NATO alliance summit in London, reports Reuters.

Reuters reported last week that Turkey was refusing to back a NATO defense plan for the Baltics and Poland until it received more support for its battle with the Syrian Kurdish YPG militia, which it views as a terrorist organization.

Ankara has said the impasse was caused by the United States withdrawing support from a separate defense plan for Turkey, covering any possible attack from the south where it borders Syria, and that it wanted the issue resolved.

NATO envoys need formal approval by all 29 members for the plan to improve the defense of Poland, Lithuania, Latvia and Estonia against any threat from neighboring Russia.
