Douglas Alexander MP, Labour’s Shadow Foreign Secretary, said:

“The Government is right to summon the Russian Ambassador to explain reports that Russian military units have crossed into Ukraine overnight.

“If proved accurate, this is a provocative and aggressive attempt by Russian forces to undermine Ukraine’s security and its territorial integrity.

“Russia must end its military support for armed separatists in Eastern Ukraine, and should work to reduce tensions in the region, not inflame them.

“The Ukraine crisis represents not just a threat to European security, but a significant geopolitical moment, and together, Europe must work harder to better influence critical calculations now being made in the Kremlin.“
