Rihanna: Brown made a mistake

Rihanna has been accused of "sanctioning" domestic violence after she showed compassion for the man who beat her.

In an interview with Oprah, which is due to be broadcast tonight in the US, Rihanna insists that Chris Brown "made a mistake" and "needed help" when, he punched her in the face, bit her and smashed her head against a car window during an argument in 2009.
