Following Russia’s invasion of Ukraine beginning Feb. 24, misinformation about the situation has spread rapidly. For example, this tweet claims that CNN was faking war footage in Ukraine.

The tweet claims that CNN started a fire in Edmonton, Canada, and made it look like they were reporting from Lviv, Ukraine. Their evidence? Firefighters seen in the background seem to be wearing uniforms with “Edmonton” on the back.

The tweet has since been deleted, but here’s another claiming the same thing.

Let’s dive into this claim and find out what’s really happening in CNN’s footage. Here’s how we fact-checked it.

Track down the original source

The best path for verifying screenshots or short clips of videos is to try and find the original source. After Googling “CNN Ukrainian fires Lviv,” I found the full CNN broadcast.

The footage seems very realistic, and given the magnitude of the explosion, it’s difficult to believe it could be staged — especially given the fact that Russia’s invasion of Ukraine has been so well-documented.

Try using a skill called geolocation

Trusting your gut or even just the vibe you’re getting from a suspicious claim online is a great way to navigate the internet and avoid being deceived. But to be sure, a media literacy tool called geolocation can help you know for sure if a video was taken in a specific area. Geolocation is the process of using information in a photo or video to attempt to confirm its authenticity, and it’s a great way to debunk suspicious photos and videos.

One great tool for geolocation is Google Maps’ Street View, which has mapped out much of the planet. If you’re unsure whether a situation happened where someone is claiming that it did, try to look for key landmarks and cross reference the background with Google Maps.

After some searching, I found the street that CNN was on the northeastern portion of Lviv. Sure enough, it looks identical to the fiery photos being broadcasted. (Watch the video above for a tutorial.)
