Russia Faces Mounting Pressure Over Rising Ukraine Violence

Russia is under increasing pressure from world leaders to help stop the violence in Ukraine, where fighting intensified along the front line between government troops and pro-Russian rebels.

The U.S. and the European Union warned that Russia may face further repercussions after a rocket attack on the port city of Mariupol on Saturday. The projectiles were launched from rebel-held territory, the U.S., NATO, and the Organization for Security and Cooperation in Europe said. The separatists blamed government forces.
