Russia has warned Lithuania and the European Union that it may take "tough measures" against them if the transit of some goods to and from the Russian enclave of Kaliningrad does not resume, Telegraph reports.

"If the situation does not stabilize in the coming days, then Russia will take tough measures against Lithuania and the EU," Maria Zakharova, spokeswoman for the Russian Foreign Ministry, said in a statement.

"The matter has taken a long time to be resolved."

Lithuania - which is a member of NATO - has banned the transit of goods subject to EU sanctions through its territory to and from the Baltic enclave.

Kaliningrad – a strategic region that is home to Russia's Baltic Fleet – has no border with mainland Russia.
