Ukraine is doing everything to release hostages and political prisoners held in Russia and the occupied territories as soon as possible, President of Ukraine Petro Poroshenko has said.

"We are doing everything possible to put pressure on the Russian President for him to finally give the order and the process we started at the end of last year, when we managed to release 74 hostages, to be continued as soon as possible. And for the Ukrainian heroes to come home as quickly as possible," Poroshenko said during the joint press conference with Estonian President Kersti Kaljulaid in Kyiv on Tuesday.

He also recalled that at all talks the issue of the release of citizens of Ukraine is being raised.

"There are no international negotiations either with our European partners, or our American partners in which we wouldn't have touched upon the necessity of immediate liberation of Ukrainian hostages illegally kept in the occupied territories and political prisoners kept in prisons in the territory of the occupied Crimea and in the territory of Russia," Poroshenko said.

According to him, this issue has been raised at today's talks.

"We've discussed this with the president, coordinated our actions, since the release of the hostages is part of the Minsk agreements, where Russia has made direct commitments to free hostages. These are Sushchenko, Sentsov, Kolchenko, and many others. They are Crimean Tatars, Ukrainian servicemen, we do not forget about," the Ukrainian president assured.
