Notre-Dame Cathedral was struck by a devastating fire and YouTube had a mistake with a new feature.
In the US and South Korea, Youtube accidentally displayed info panel related to the 9/11 attacks.
The panels are meant to combat misinformation and conspiracy theories, reports Business Insider.
The feature is intended to link viewers to verified sources on trending news subjects.
The panels were automatically triggered as the fire at Notre-Dame Cathedral captured global attention.
YouTube says it has disabled the panels for live streams related to the fire.
