Facebook takes down far-right groups days before Spanish election
Investigation uncovered networks reaching 1.7m people that were spreading fake news
Facebook has taken down several networks that were spreading far-right content to nearly 1.7 million people in Spain, days before national elections that are expected to see a surge in support for the far-right Vox party.
The networks were uncovered in an investigation by the campaign group Avaaz, and taken down only after it presented Facebook with its findings.
