Oprah cancels Columbine anniversary special

Oprah Winfrey has cancelled a TV special to mark the 10th anniversary of the Columbine High School massacre out of respect for the victims and their families.

Twelve students and a teacher were killed when Eric Harris and Dylan Klebold went on a killing spree at the Littleton, Colorado school in 1999, before committing suicide, and Winfrey had planned to mark the tragic date with a show dedicated to the tragedy.

However, in a post on her website, she explains the show, which was to air in the US on Monday, has been scrapped.

"After reviewing it, I thought it focused too much on the killers," she said. "Today, hold a thought for the Columbine community. This is a hard day for them."
