Amid reports of fighting in Ukraine over the weekend, one video posted on social media captured an apocalyptic scene: multiple fires raging on a highway outside of an apartment building as smoke billowed and loud pops rang through the night.

It was gripping footage, but journalists who looked at it knew that many similar videos have turned out to not be what they seem: A clip of a supposed missile launch in Ukraine had actually been filmed in Turkey in 2016; an Instagram post purporting to show Russian planes over Kyiv actually depicted a Russian military flyover two years ago in Moscow.
