Sky News reports in one of its famous 'explainers':

We've told you that the British Council building was damaged in Russia's overnight attack on Kyiv, and that the UK has summoned the Russian ambassador as a result (see 13.20 post).

The British Council is the UK's international organisation for cultural relations and educational opportunities.

It was founded in 1934 to create "friendly knowledge and understanding between the people of the UK and other countries", its website says.

The founding Royal Charter outlined their mission as 'promoting abroad a wider appreciation of British culture and civilisation'.

Wikipedia (!) says: The organisation has been called a soft power extension of UK foreign policy, as well as a tool for propaganda...

Well! How about that.

An alternative explanation is that the British Council is an organization that promotes great British values - values that include supplying weapons all over the world to people we happen to like at the time in order to kill people we happen not to like at the time. 

Maybe this is the explanation that will be given to the Russian ambassador in this, a clear case of the new trend of 'secondary targeting'.
