Russia said Wednesday its military fired warning shots and dropped bombs in the path of a British warship in the Black Sea that entered waters claimed by the Kremlin off the coast of Russian-annexed Crimea. Britain denies the account and accused Russia of sowing discord with a false story.

The naval tensions came on the same day that German and French leaders called for a “reset” of relations between the European Union and Russia, with plans under consideration to invite Russian President Vladimir Putin to a summit with EU leaders.
