In the last couple of hours, the Russian government has announced that it has issued a travel ban against 13 British officials.
Among them: Prime Minister Boris Johnson, Foreign Secretary Liz Truss, and Defence Secretary Ben Wallace.
The latter two were here in Moscow in late January, aimed at trying to de-escalate the tensions between Russia and Ukraine to no avail.
Now the Russian Ministry of Foreign Affairs says that they have been issued with this ban,
because this is "a response to London's unbridled information and political campaign".
It also says that the British leadership is deliberately aggravating the situation around Ukraine.
Now these are only 13 officials who have been named, they say that the list will be expanded.
But that compares to what the UK government says is 1,400 Russian officials, individuals and businesses that have been hit by UK sanctions so far since February 24.
So certainly there is likely to be more retaliation from the Russian side.
There have been a number of countries issuing bans against Russian officials.
It is the sanctions against banks, against certain industries that will do much more damage to Russia and Russia's economy.
