Facebook on Thursday announced an expansion of several initiatives to combat the spread of misinformation on the social network used by more than 2 billion people.

In a company blog, Facebook acknowledged that fake news reports and doctored content have increasingly become image-based in some countries, making it harder for readers to discern whether a photo or video related to a news event is authentic. The company said it has expanded its fact-checking of traditional links posted on Facebook to photos and videos. Partnering with third-party experts trained in visual verification, the company will also flag images that have been posted on Facebook in a misleading context, such as, for example, a photo of a previous natural disaster or shooting that is displayed as a present-day event.
