In February 2005, the mission deplores the deaths of 9 Bangladeshi UN troops killed during an ambush in Ituri. The actions of the Ituri and Kivu Brigades become more robust and the pressure rises on all armed groups. Thomas Lubanga Dyilo, the leader of the Union of Congolese Patriots, and other militia leaders were arrested by Congolese authorities and imprisoned in Makala, Kinshasa. Lubanga was accused of having ordered the killing of the peacekeepers in February 2005 and of being behind continuous insecurity in the area. On 10 February 2006, the International Criminal Court issued an arrest warrant for Lubanga for the war crime of "conscripting and enlisting children under the age of fifteen years and using them to participate actively in hostilities". The Congolese national authorities transferred Lubanga to ICC custody on 17 March 2006.
