Due to the war situation between Ukraine and Russia, the ability to display and monetize Google Ads for related content has been temporality stopped by Google.

Therefore, if you already have Google Ads and monetization enabled for content related to the Ukraine crisis, it is best to stop immediately. Especially if you have a YouTube channel that has content on that, keep monetization off in the settings of those videos. This will protect your Google Ads and Google AdSense accounts from policy violations.
