Secretary General of the Council of Europe Thorbjorn Jagland is assisting in the rapid release of Ukrainians detained in Russia, Ukrainian Foreign Minister Pavlo Klimkin has said.

"It is very important for me that Mr. Jagland supports and is actively working on the release of political prisoners who are now held in Russia," he said after talks with Jagland in Kyiv on Tuesday.

He said that the issue concerned Ukrainian female pilot Nadia Savchenko, film director Oleh Sentsov and others.

"Together, we will never stop until the release of political prisoners, and the Council of Europe's assistance in this context is absolutely critical," Klimkin said.

He also said that the sides had discussed the preparation of a new cooperation plan for 2015-2017 between Ukraine and the Council of Europe.

Jagland, in turn, noted that the Ukrainian people and the Ukrainian state "faced an open military aggression on Ukrainian territory."

"This conflict, this situation is a situation of the present day. This conflict might be the case in the past, but not now," he said.

He said that the violation of Ukraine's territorial integrity and rule of law was obvious.

"The clear violation of Ukraine's territorial integrity, as well as the rule of law, on the territory of a member country of the Council of Europe is obvious. The charter of the organization clearly states that countries are obliged to peacefully resolve all conflicts on the territory of member countries," Jagland said.

He also noted the importance of achieving a de-escalation of the situation in a peaceful way and resolving humanitarian problems not only in the eastern regions, but also in respect of persons who have been forced to leave these regions.

"I will further travel to Moscow, and there I will speak about obligations undertaken by the member states of the Council of Europe, statutory obligations and obligations on observing human rights," he said.
