Unmasked: The 18 Russian spies who mounted series of attacks on UK

Dozens of Russian spies have been sanctioned by the government - including those responsible for targeting Yulia Skripal five years before her attempted murder in Salisbury.

The Foreign Office has announced that three units of the Russian military intelligence agency (GRU) have been hit with sanctions, alongside 18 military intelligence officers.

GRU officers attempted to murder Yulia Skipal and her father Sergei using the deadly Novichok nerve agent in Salisbury.

The 18 military intelligence officers have been targeted because of a sustained campaign of malicious cyber activity over many years, including in the UK, the Foreign Office said.

The government also accused the GRU of using cyber and information operations to "sow chaos, division and disorder in Ukraine and across the world".

One of the groups sanctioned, Unit 26165, conducted online reconnaissance to help target missile strikes against Mariupol, including the bombing of Mariupol Theatre where hundreds of civilians, including children, were murdered.

Other military officers who have been sanctioned previously targeted Yulia Skripal's mobile phone with malicious malware known as X-Agent.

The Skripals had moved to the UK after Sergei Skripal became a double agent, secretly working for the UK. He was tried for high treason and imprisoned in Russia - and later exchanged in a spy swap.

But five years after Yulia's phone was targeted, the pair were poisoned with the nerve agent, Novichok, in Salisbury. Russia has always denied being involved in the chemical attack.

Foreign Secretary David Lammy said: "GRU spies are running a campaign to destabilise Europe, undermine Ukraine's sovereignty and threaten the safety of British citizens," Foreign Secretary David Lammy said.

"The Kremlin should be in no doubt: we see what they are trying to do in the shadows and we won't tolerate it."

He said the UK was taking "decisive action" with the sanctions against Russian spies.

"Putin's hybrid threats and aggression will never break our resolve. The UK and our allies' support for Ukraine and Europe's security is ironclad."

• Aleksandr Vladimirovich Osadchuk
