A white man suspected of killing nine people in a Bible study group at a historic black church in Charleston, South Carolina, was arrested yesterday. Officials are investigating the attack as a hate crime.

Jurors in Charleston, South Carolina, convicted a 15-year-old boy who claimed an antidepressant drug drove him to murder his grandparents, rejecting the first defence in the United States in which a juvenile claimed the effects of the drug caused him to kill.
