sentences:  The AU attempted to mediate in the early stages of the 2011 Libyan civil war, forming an "ad hoc" committee of five presidents (Congolese President Denis Sassou Nguesso, Malian President Amadou Toumani Touré, Mauritanian President Mohamed Ould Abdel Aziz, South African President Jacob Zuma, and Ugandan President Yoweri Museveni) to broker a truce.However, the beginning of the NATO-led military intervention in March 2011 prevented the committee from traveling to Libya to meet with Libyan leader Muammar Gaddafi.As a body, the AU sharply dissented from the United Nations Security Council's decision to create a no-fly zone over Libya, though a few member states, such as Botswana, Gabon, Zambia, and others expressed support for the resolution.
