A RUSSIAN naval destroyer has been escorted from the Moray Firth by a Royal Navy frigate.

The incident on Saturday came just days after Prime Minister Theresa May launched an attack on Russia for influencing foreign governments and planting fake news online.

It was also revealed over the weekend that fake twitter accounts - many of them thought to be linked to Russian attempts to destabilise the West - posted almost 400,000 automated messages about Scottish independence in just 18 months.

HMS Somerset, a Plymouth-based Type 23 frigate, detected and monitored the movements of the Russian warship Vice Admiral Kulakov and her supporting tanker.

The Herald:

The British vessel had been engaged in trials of her cutting-edge sonar equipment when she received the call to locate and shadow the Russian units.

She arrived in the Moray Firth on Saturday and escorted the ships through UK waters and north along the coast of Norway before returning to her original task.

Commander Timothy Berry, HMS Somerset's Commanding Officer, said: "As with all Royal Navy ships operating in UK waters, HMS Somerset was at a high state of alert to deal with any maritime security task such as this.

The Herald:

"Monitoring transits of non-NATO warships through UK territorial waters is part of what the Royal Navy does all year round to keep Britain safe.

"We now continue with our original tasking having seen the Russian ships safely through the UK's area of interest."

The Vice Admiral Kulakov is a Russian Udaloy-class destroyer. It is thought she was returning from a deployment in the Mediterranean. The warship was accompanied by a tanker, which is standard procedure for Russian ships.

The Herald:

It was not the Kulakov's first visit to UK waters as the destroyer was also shadowed by HMS Somerset from the same position in the Moray Firth in March 2016.

Russian warships of the northern and Baltic fleets routinely pass through UK territorial waters en route to or from deployments in the Mediterranean and Gulf regions.
