The teenage children of one of the victims of the shooting at a church in Charleston, say they've forgiven their mother's killer.

Speaking for the first time since the attacks, they told the BBC they wanted to focus on moving on in a positive way.

Their mother, Sharonda Singleton, 45, was one of nine people shot dead.

Suspect Dylann Roof, 21, is now in custody.
