"Russia's armed aggression has claimed the lives of 13,000 people and more than 28,000 people have been injured. And this figure also includes 298 passengers of flight MH17, which was shot down by the Russian military from the Buk missile system in July 2014," Poroshenko added.

According to him, more than 1.8 million residents of Crimea and Donbas had to leave their homes as a result of Russian aggression and occupation.

"Once the peaceful life of people in those regions turned into a nightmare accompanied by fear and terror," he said.
