"I congratulate Malala Yousafzai and Kailash Satyarthi - two of the world's greatest champions for children -- on being awarded the 2014 Nobel Prize for Peace," Ban said in a statement issued here.
The UN Secretary General said Satyarthi, 60, has been at the forefront of a worldwide movement for justice, global education and a better life for millions of children trapped in exploitative child labour.
He said the Indian social activist's leadership, commitment and personal sacrifice over many decades have helped raise public awareness, mobilise opinion leaders, and galvanise society.
Describing Malala, 17, as a "brave and gentle" advocate of peace, Ban said the Pakistani teenager has with her courage and determination, shown what terrorists fear most - "a girl with a book".
