Russia said on Monday it saw nothing new in comments by leaders of the Group of Seven (G7) taking a tough line on Russia over sanctions and suggested there were differences among its member states, Reuters reported. British Prime Minister David Cameron and European Council President Donald Tusk both said they hoped the G7, meeting in Germany, would present a united front on sanctions towards Russia over the Ukraine crisis. "Yes we paid attention to the latest declarations on sanctions. These are not new," Kremlin spokesman Dmitry Peskov told reporters.
