A London mother has been found guilty of subjecting her 3-year-old daughter to female genital mutilation in Britain's first conviction for the practice, more than 30 years after it was outlawed.

The Ugandan mother of two, who cannot be named for legal reasons, could face up to 14 years in prison. Justice Philippa Whipple adjourned sentencing Friday until March 8.

Police and anti-FGM campaigners said the conviction sent a strong message that FGM is child abuse and will be prosecuted.
