LONDON - Actress Freida Pinto of "Slumdog Millionaire" fame has joined forces with girls' rights campaigners in calling for an end to the practice of female genital mutilation.

The Indian actress, an ambassador for an international children's development organization, called last week for more progress to abolish the practice as she addressed Britain's inaugural "Girl Summit."

UNICEF, the United Nations' children agency, said some progress has been made on ending female genital mutilation, most commonly practiced in Africa and the Middle East. It is still highly prevalent in Egypt, Sudan, Mali and Somalia.

The agency and Britain's government hope the summit will help galvanize action to end the practice within a generation.

Britain's government announced new measures to tackle the problems in the U.K.

The one-day event also focused on child marriages, which UNICEF says affects 700 million women, especially in sub-Saharan Africa and South Asia.

Malala Yousafzai, the teenager who was shot by the Taliban and recovered to become a global campaigner for education and women's rights, also addressed the summit.
