Principles proposed that African governments commit to OPAC, which was being negotiated at the time, and raise the minimum age for military recruitment from 15 to 18. The Principles also defined a child soldier to include any person under the age of 18 who is "part of any kind of regular or irregular armed force or group in any capacity ... including girls recruited for sexual purposes..." In 2007, the Free Children from War conference in Paris produced the Paris Principles, which refined and updated the Cape Town Principles, applied them globally, and outlined a practical approach to reintegrating current child soldiers. Central African Republic The use of children by armed groups in the Central African Republic has historically been common. Between 2012 and 2015 as many as 10,000 children were used by armed groups in the nationwide armed conflict and children were still being used. The mainly Muslim Séléka coalition of armed groups and the predominantly Christian Anti-balaka militias have both used children in this way; some are as young as eight. In May 2015 at the Forum de Bangui (a meeting of government, parliament, armed groups, civil society, and religious leaders), a number of armed groups agreed to demobilize thousands of children. In 2016 a measure of stability returned to the Central African Republic and, according to the United Nations, 2,691 boys and 1,206 girls were officially separated from armed groups. Despite this, the recruitment and use of children for military purposes increased by approximately 50 percent over that year, mostly attributed to the Lord's Resistance Army. Democratic Republic of the Congo Thousands of children serve in the military of the Democratic Republic of the Congo (DRC) and various rebel militias. It has been estimated that more than 30,000 children were fighting with various parties to the conflict at the height of the Second Congo War. It was claimed in the film Kony 2012 that the Lord's Resistance Army recruited this number. Currently, the DRC has one of the highest proportions of child soldiers in the world. The international court has passed judgment on these practices during the war. Thomas Lubanga Dyilo, one of the warlords in the DRC, has been sentenced to 14 years in prison because of his role in the recruitment of child soldiers between 2002 and 2003. Lubanga directed the Union of Congolese Patriots and its armed wing Patriotic Forces for the Liberation of
