Russia says it has lodged protest with EU envoy over Kaliningrad 'blockade'

- Russia's foreign ministry said on Tuesday that it summoned the European Union's ambassador to Moscow Markus Ederer over what Moscow calls "anti-Russian restrictions" on goods transiting between Kaliningrad and the rest of Russia.

In a statement, it called for transit via the region to be restored "immediately" and vowed to retaliate if the situation does not improve.

EU member Lithuania has shut a rail corridor from Russia to its exclave to certain basic goods including construction materials, metals and coal in response to new EU sanctions that came into force on Saturday.
