In March 1993, the UN Security Council authorized a new mission, UNOSOM II, which was endowed with enforcement powers under Chapter VII of the UN Charter to establish a secure environment throughout Somalia. However, operations turned sour after the Battle of Mogadishu on October 3, 1993, when US forces attempted to launch an attack on the Olympic Hotel in search of Mohamed Farrah Aidid. The subsequent combat resulted in the deaths of 18 US soldiers and a further 83 casualties. After the battle, the bodies of several US casualties of the conflict were dragged through the streets of Mogadishu by crowds of local civilians and members of Aidid's Somali National Alliance.
