The US has slapped sanctions on five Russian companies and three Russian individuals for allegedly aiding Russia’s main intelligence agency.

Treasury Secretary Steven Mnuchin said the measures were to counter “malicious actors” working to “increase Russia’s offensive cyber-capabilities”.

The sanctioned entities and individuals are prohibited from any transactions involving the US financial system.

The move is in response to alleged Russian cyber-attacks on the US.

In addition to being barred from the US financial system, the measures mean American citizens and companies cannot do business with the Russian entities.

“The entities designated today have directly contributed to improving Russia’s cyber and underwater capabilities through their work with the FSB [Federal Security Service] and therefore jeopardise the safety and security of the United States and our allies,” Mr Mnuchin said in a statement on Monday.
