New Delhi (CNN Business) For the fourth time in less than a year, Facebook has removed dozens of accounts, pages and groups linked to the Myanmar military, saying they engaged in suspicious activity and used fake profiles.

The company took down 89 Facebook accounts, 107 pages and 15 groups, as well as five Instagram accounts, from the Southeast Asian country for "engaging in coordinated inauthentic behavior," Nathaniel Gleicher, Facebook's head of cybersecurity policy, said in a blog post on Wednesday.

"The people behind this activity used fake accounts ... to promote their content, increase engagement, and manage groups and pages," Gleicher said. "Our investigation found that some of this activity was linked to individuals associated with the Myanmar military," he added.

Facebook FB has taken down suspicious networks linked to Myanmar's military three other times in the past year, including more than 200 accounts and more than 500 pages. In August 2018, it banned Myanmar's military chief and the country's military television network after a United Nations report found that they "committed or enabled serious human rights abuses in the country."

The company has found itself at the center of what has been described as a genocide in Myanmar, with activists saying its platforms are used to spread misinformation and hate speech , particularly against the country's Rohingya Muslim minority. Facebook has acknowledged that it was "too slow" to react to the abuse of its platform and "can and should do more."
