Russian invasion of Ukraine

apparently will only affect foreign issued cards and purchases outside Russia and have no impact on Russian people using them to buy goods/withdraw cash in Russia itself

San Francisco-based Visa said in a statement that it will immediately
begin working with clients and partners in Russia to stop all
transactions over the coming days. Once the process is completed,
transactions by Visa cards issued in Russia will no longer work
outside the country, and cards issued elsewhere in the world will not
work within Russia.

Well, hope those Russian tourists stuck abroad took off some cash
