There is more fighting between government forces and Russian-backed rebels in eastern Ukraine, despite the cease-fire agreed to over the weekend.  Both rebels and the Kiev government accused each other of breaching the cease-fire.

Ukraine's National Security and Defense Council on Sunday said that rebels in Donetsk tried to attack the airport, which government forces have held since May. 

“Listen to the sound of the ceasefire,” joked an armed rebel to a reporter. “There’s a proper battle going on there.”

And renewed shelling on government roadblocks leading into the strategic port city of Mariupol on the Sea of Azov killed at least one woman and injured three other people. 

Amnesty International is accusing both the rebels and the Ukrainians of war crimes.  But the human rights group says Moscow is clearly pushing the conflict.  Amnesty published satellite images showing a build-up of Russian armor and artillery in eastern Ukraine.

“Our evidence shows that Russia is fuelling the conflict, both through direct interference and by supporting the separatists in the east.  Russia must stop the steady flow of weapons and other support to an insurgent force heavily implicated in gross human rights violations,” said Amnesty International secretary-general Salil Shetty.

The Kremlin denies the charges.
