An estimated 20,000 children took part in hostilities during the 1990s, including the 1994 Rwanda genocide when many children were involved in committing atrocities. 5,000 children were in the national army, while others, including many street children, joined or were made to join armed groups. After the genocide, 4,500 children were detained on suspicion of participating in atrocities, and were incarcerated for several years without charge or trial; some were sent to the Gitagata Re-Education Centre for males below 14 years of age. In the late 1990s, children were widely recruited again, often by force, to fight in the Democratic Republic of the Congo (DRC).
