Ukraine’s interior minister says 30 pro-Russian insurgents and four soldiers have been killed in the eastern city of Slovyansk as Ukraine continues an assault to reassert control. Ukraine has also sent an elite national guard unit to the southern port city of Odessa, where 46 people died Friday in clashes between nationalist and pro-Russian forces. White House spokesperson Jay Carney condemned the violence on Monday.

Jay Carney: “The events in Odessa dramatically underscore the need for an immediate de-escalation of tensions in Ukraine. The violence and efforts to destabilize the country must end. And we again call for the immediate implementation of the commitments made in Geneva on April 17th.”
