The European Wall program to strengthen the Ukrainian-Russian border has been fulfilled only by 20%, Ukrainian Prime Minister Arseniy Yatseniuk has said.

"We've fulfilled only around 20% of works required to be finished on the eastern border. The total length [of the structures] that are to be built is 2,000 km, and we don’t control 400 km due to the Russian aggression," Yatseniuk said in the parliament on Tuesday.

He said that over 200 km of antitank ditches were dug, over 70 km of fences, 32 watchtowers and several points of power control over the state border were built.
