President of the European Council Donald Tusk has again called on Russia to free Ukrainian captive pilot, Member of Parliament Nadia Savchenko and all other Ukrainian citizens who have been illegally imprisoned in Russia.

"We have also discussed the issue of Nadia Savchenko, who is still in illegal detention in Russia. Let me in this context reiterate the call by the EU for her immediate release, along with Oleh Sentsov and all other illegally detained Ukrainian citizens," Tusk said during a joint statement with Ukrainian President Petro Poroshenko and President of the European Commission Jean-Claude Juncker in Brussels on Thursday.

Tusk said that the EU would continue support all the efforts aimed at the implementation of the Minsk agreements.

"We continue to support the diplomatic efforts aimed at implementing the Minsk agreements. Further determined efforts are needed. Our economic sanctions against Russia remain linked to the complete fulfillment of the Minsk Agreements," he said.
