Russia on Tuesday warned Lithuania that its decision to partially block the transport of goods to the Russian exclave of Kaliningrad would have serious consequences.

"Of course, Russia will respond to hostile actions. Appropriate measures are in the works, and will be adopted in the near future,” Russian security council secretary Nikolai Patrushev said during a visit to Kaliningrad, according to local media.

They will “have a serious negative impact on the people of Lithuania,” he added.
