The National Security and Defense Council of Ukraine ordered the government to carry an one-side demarcation of the Ukrainian-Russian border in terms of existing threats to national security, said NSDC Secretary Andriy Parubiy.

"The Cabinet of Ministers of Ukraine was charged to organize the one-side demarcation of the Ukrainian-Russian state border, to provide its proper technical arrangements in accordance with today's threats to the national security," he said after a meeting of the NSDC in Kyiv on late Monday.
