Russia has accused Britain of being drawn “too deep” into the conflict in Ukraine, warning that it risks a “dangerous” escalation of the crisis.

Andrey Kelin, the Russian ambassador to the UK, claimed British “specialists” had been involved in an audacious drone attack on Russia’s Black Sea fleet at the weekend in which three warships were reportedly damaged, including the flagship HMS Makarov.
