A huge cyber-attack which knocked out more than 2,000 websites in the country of Georgia last year was carried out by Russia, according to Georgia, the UK and the US.
The UK government says that the GRU (Russian military intelligence) was behind the "attempt to undermine Georgia's sovereignty".
Foreign Secretary Dominic Raab described it as "totally unacceptable".
Russia's Foreign Ministry denied any involvement, the RIA news agency said.
The UK's National Cyber Security Centre (NCSC) found that the GRU was "almost certainly" behind the attacks, which affected pages including Georgia's presidential website and the country's national TV broadcaster. It said the attack was the first significant example of GRU cyber-attacks since 2017.
Previous GRU cyber-attacks
- December 2015: An attack on part of Ukraine's electricity grid left 230,000 people without power for between one and six hours
- December 2016: A malware designed specifically to disrupt electricity grids led to a fifth of the Ukrainian capital Kyiv losing power for an hour
- June 2017: A destructive cyber-attack targeted the Ukrainian financial, energy and government sectors. It also affected other European and Russian businesses
- October 2017: The Kyiv metro and Odessa airport, as well as Russia's central bank and two Russian media outlets, were disrupted after ransomware encrypted hard drives

The UK said Russia had sought to "sow discord and disrupt the lives of ordinary Georgian people".
"The Russian Government has a clear choice: continue this aggressive pattern of behaviour against other countries, or become a responsible partner which respects international law," Mr Raab said.
US Secretary of State Mike Pompeo also condemned the attacks, saying: "The United States calls on Russia to cease this behaviour in Georgia and elsewhere."
In many cases, website homepages were replaced with an image of former President Mikheil Saakashvili, and the caption "I'll be back".
This is the latest element of an ongoing campaign of pressure by the UK against Russian intelligence since the poisoning of the former Russian spy Sergei Skripal in Salisbury two years ago. The aim is to try and deter Russian activity by exposing it.
A notable aspect of this attribution is that it relates to events which took place relatively recently, in October 2019. One of the targets was Georgian broadcasters.
The GRU's targeting of broadcasters goes back at least to 2015 and a takedown of the French TV5Monde channel. That led to concern about what they might do against other broadcasters in other countries.
This is seen as part of Russia's tactics of hybrid warfare, or grey-zone activities, which are designed to destabilise countries.
The problem for the UK, though, is that so far there is little sign of the GRU being deterred.
A key test will come with the US election this year, and whether it attempts to interfere in that as it was accused of doing in 2016.
