Facebook Inc said on Wednesday it has reached an agreement with news agency Reuters, a unit of Thomson Reuters Corp, to fact-check content posted on the social media platform and its photo-sharing app Instagram.

Under pressure to remove fake news on its platform ahead of the US presidential elections, Facebook started a US pilot program in December to detect misinformation faster.

The move came after US intelligence agencies said that social media platforms were used in a Russian cyber-influence campaign aimed at interfering in the 2016 US election – a claim Moscow has denied.
