After the fragile peace deal was signed on Thursday, growing numbers of casualties continue in the pro-Russian rebel-held areas in eastern Ukraine, jeopardizing the deal and making it more likely to fail. The long dispute between Ukraine and Russia still continues as the disagreements are still on the ground.

While Ukrainian Foreign Minister Pavlo Klimkin denied any obligations of Ukraine regarding the possibility of constitutional reform and decentralization, Russia wants Ukraine to fully implement the Minsk Accords.

"I don't want anyone to have any illusions and so I am not seen as a naive person – we are still a very long way from peace," Ukraine President Petro Poroshenko said during a visit to a military training ground on Friday. "Nobody has a strong belief that the peace conditions that were signed in Minsk will be implemented strictly."

The Russian position is still too far removed to reconcile, the conflicting interest of Russia in the Ukrainian crisis is preventing a sustainable settlement between Kiev and the eastern Ukrainian separatists. The months-long crisis in Ukraine's east is still unresolved despite a series of mediating talks. Previous talks have not produced a breakthrough over issues relating to the settlement of the crisis in Ukraine so far.

After all-night negotiations between Russia, Ukraine, France and Germany, a deal was achieved to restore stability and peace in rebel-held areas in eastern Ukraine. The Ukrainian government, Moscow and the representatives of pro-Russian separatists agreed on a road map for peace during talks in Minks with the leaders of Russia, France and Germany agreeing to support the deal.

Meanwhile, Ukrainian armed forces and Russian-backed rebels fought fiercely for control of a strategic railway junction. At least 15 people were reportedly killed in east Ukraine in new shelling on Friday. In the face of the growing civilian death toll, both sides accused each other of killing civilians.

Since hostilities erupted in eastern Ukraine more than 5,500 people have been killed during heavy clashes between armed groups. According to the U.N., the death toll has sharply increased and more than 2 million and Ukrainians were forcibly displaced due to worsening humanitarian conditions in rebel-held areas where heavy fighting has turned the cities into battle zones.
