Russia’s defense ministry warned on April 15 it will intensify attacks on the Ukrainian capital Kyiv in response to strikes on Russian soil, after accusing Ukraine of targeting Russian border towns.

“The number and scale of missile strikes against targets in Kyiv will increase in response to any terrorist attacks or sabotage committed by the Kyiv nationalist regime on Russian territory”, - the ministry said in its daily update.

It added that Russian troops hit a “military” factory outside Kyiv late Thursday using Kalibr sea-based long-range missiles.

“As a result of the strike on the Zhulyansky machine-building plant Vizar, the workshops for the production and repair of long-range and medium-range anti-aircraft missile systems, as well as anti-ship missiles, were destroyed. S-400 missile system shot down a Ukrainian Mi-8 helicopter that carried out an attack on civilians in the locality of Klimovo in Bryansk region on April 14”, - the ministry said.
