Extensive bomb haul at US gunman's home

Bomb squad police were detonating a huge explosives haul today at the home of a man accused of shooting dead eight people in Virginia's worst mass killing incident since 2007.

Security guard Christopher Speight, 39, gave himself up yesterday morning after leading police on an 18-hour manhunt following the killings at a house in rural Appomattox, 100 miles south west of Richmond, where deputies found a fatally-wounded man and seven bodies.
