19 killed in Crimea student shooting

A student at a polytechnic college in Russian-annexed Crimea has shot and killed at least 19 people - and wounded as many as 50 more before turning the gun on himself. Surveillance footage has emerged of the alleged shooter Vladislav Roslyakov - a student at the school - dressed similar to one of the shooters of the infamous Columbine massacre. Students outside the college could hear gunshots coming from inside. Moscow correspondent Dan Ashby talks to Susie Ferguson
