Another Russian warship has been escorted by the Royal Navy through British waters at a time of heightened diplomatic tension between Moscow and London.

The frigate, Yaroslav Mudry, was encountered by Navy frigate HMS Sutherland at the entrance to the English Channel and then monitored as it sailed through UK waters.

It comes at a time of diplomatic strife, with British ministers lining up to condemn Russia's support for Syrian president Bashar Assad as his regime's forces won a brutal victory in the four-year battle for Aleppo.
