Nobel Peace Prize presented to female trio in Oslo
The 2011 Nobel Peace Prize has been presented to three women at a ceremony in the Norwegian capital, Oslo.
This year's award was won jointly by Ellen Johnson Sirleaf, the president of Liberia, Leymah Gbowee, the Liberian peace activist, and Yemeni pro-democracy campaigner Tawakkol Karman.
They were recognised for their "non-violent struggle" for women's safety and for women's rights to participate in peace-building work.
