Yuri Dovgal, deputy director of the secondary school which Dias Kadyrbayev attended in 2008 and 2009, speaks during an interview with Reuters in Almaty May 2, 2013. Kazakhstan said on Thursday it condemned any form of terrorism and was cooperating with the United States after two of its citizens were charged with interfering with the investigation of the Boston Marathon bombing. Students Azamat Tazhayakov and Dias Kadyrbayev, both 19, were charged by U.S. authorities with conspiring to obstruct justice by hiding a backpack and fireworks they found in the dorm room of one of the suspected bombers.
