Audio slideshow: The Columbine shootings

The murder in April 1999 of 13 people at a Colorado high school - by two heavily armed pupils - sent shockwaves across the US.

After their shooting spree, Eric Harris, 18, and Dylan Klebold, 17, killed themselves.

Here - using BBC Radio archive - we recall how events unfolded that day.
