NATO Secretary General condemned Russia's moves to  incorporate Crimea into the Russian Federation.

In a statement issued on Tuesday, Anders Fogh Rasmussen said Russia disregarded all calls to step back into line with international law and continues down the dangerous path.

“There can be no justification to continue on this course of action that can only deepen Russia's international isolation. Crimea's annexation is illegal and illegitimate and NATO Allies will not recognise it,” he said.

Besides, Rasmussen expressed concern over the reports of the death of one Ukrainian officer. 

“It is urgent that all sides show restraint and take all possible steps to avoid further escalation”.
