Facebook struggles as Russia steps up presence in unstable west Africa

Increasingly sophisticated efforts to influence opinion are making it harder to establish whether they breach Facebook's policies

Facebook is struggling to contain pro-Russian and anti-western posts that are contributing to political instability in west Africa, investigators and analysts have said.

The platform, which has expanded rapidly across the continent in recent years, has made significant investment in content moderation, but still faces enormous challenges in curbing deliberate disinformation campaigns. One major area of concern is the strategically important Sahel region, which has suffered a series of military takeovers over the last 18 months.
