Columbine massacre remembered, twenty years on

Twelve students and a teacher were killed on April 20, 1999, when two teenagers armed with an assortment of weapons and home-made bombs went on the rampage at the school, whose name has become synonymous with school shootings. Only last year, 17 students and staff were killed when an ex-pupil went on the rampage at Marjory Stoneman Douglas High School in Florida, while 27 people, mostly children, were killed at Sandy Hook elementary school in 2012 and 32 at Virginia Tech university in 2007.
