Two countries on Nato’s eastern flank have warned that Russia is preparing a possible “provocation” in the Baltic states or Poland in an effort to test the cohesion of the western military alliance.

Western sources also fear there could be danger on the horizon because the Kremlin is coming under pressure from Ukraine’s campaign of long-range attacks on targets near Moscow and St Petersburg.
