EU country blames Russia for new sabotage attack by October 31?

What counts

The market resolves to Yes if an EU member state’s government officially blames Russia for a physical sabotage attack on its own soil before October 31 at 11:59 PM ET. It resolves to No if no such official attribution occurs by that deadline, or if the claim comes from anonymous sources, other countries, or international bodies like NATO.
