at the scene this afternoon riddled with bullet. today's shooting the second deadly attack in the last four days. joining me is leon aaron, director of russian studies at the american enterprise institute. also author of "roads to the temple." also joining me is michael kay of the british military. he has a background of looking at ukraine politics and post-soviet union politics. leon, if i can start with you, we've had disappointing developments in the last 24 to 48 hours. you have a deadly clash between what appears pro-russian forces and pro-kiev forces. and you have no compliance with this agreement worked out between the u.s. and russia, ukraine and others in geneva on thursday for those pro-russian militants to vacate buildings they occupy. doesn't look good for that
