Lithuania will be ready if Russia disconnects it from the regional power grid in retribution for preventing rail supplies of some Russian commodities to Moscow’s exclave of Kaliningrad, its president told Reuters, but no military clash is likely.

He remarked after the Kremlin threatened Lithuania on Tuesday that Moscow will retaliate to the EU-sanctioned embargo on goods transit to Kaliningrad in such a way that Baltic civilians would suffer.

Lithuania barred the passage of products sanctioned by the European Union over its territory to and from Kaliningrad, citing EU sanction regulations.

Kaliningrad is sandwiched between NATO members Poland and Lithuania and supplied by rail via the territory of Lithuania.

Lithuania shut the route for transport of steel and other ferrous metals from mainland Russia on Friday, saying it had to do so under EU sanctions that took effect that day.
