Ukraine Prime Minister, Arseniy Yatsenyuk, has vowed to ban Russian airlines from flying into the country, as part of sanctions over Moscow’s support for rebels in the East.
Kiev said that the measures would take effect on October 25 and would include major Russian airlines.
Russian transit flights will also be banned if the planes carry military personnel or dual-use goods.
Moscow has, however, described the move as “an act of madness”, promising a firm response.
Last week, Ukraine imposed sanctions against 400 people and 90 legal entities – most of them from Russia, held responsible for Moscow’s annexation of Crimea in March 2014 and the ongoing conflict in Eastern Ukraine.
