Egypt's Interior Ministry says it has arrested three people who are running 23 Facebook pages, accusing them of using the website to incite against state institutions.

The ministry accused two men, both age 27, and a 25-year-old women of being members in the Muslim Brotherhood. Egypt outlawed the Brotherhood in 2013 after the military overthrew elected Islamist President Mohamed Morsi.

Authorities have shown public concern over calls on social media to organize protests on Jan. 25 to mark the fifth anniversary of the 2011 uprising that removed longtime autocrat Hosni Mubarak. Social media, particularly Facebook and Twitter, played a large part in organizing the Jan. 25 uprising, and other protests since then.

Last week, President Abdel-Fattah el-Sissi warned against any such protests, saying they could result in chaos.
