29 people were killed over the weekend in separate mass shootings in Dayton, Ohio and El Paso, Texas.
During these types of tragic events, journalists are confronted by a huge amount of misinformation which makes reporting even more challenging.
Cristina Tardáguila, founder of Brazilian fact-checking agency Agência Lupa, spoke to Spanish platform Maldita.es, French newspaper Libération and France 24's 'Les Observateurs', about their tips on spotting misinformation and disinformation on social media during terror attacks.
In this article, Tardáguila stresses the importance of rigorously checking reports, photos and video posted online before publication.
"Don’t trust anonymous sources. Don’t share anonymous photos or videos. If a story doesn’t have a source nor a link, it is not a story," she advises.
