A 3-day extension of a ceasefire in eastern Ukraine has failed to bring fighting to a halt.
Ukrainian President Petro Poroshenko announced on Friday that a weeklong unilateral ceasefire would be extended until Monday. He made the announcement after returning from Brussels where he signed a free trade agreement with the European Union.
EU leaders have called on pro-Russian militants to take steps by Monday to ease tensions. They say they are ready to impose additional sanctions on Russia unless the country takes concrete measures toward peace.
The militants said on Friday that they had agreed to the ceasefire extension during talks with government officials in Donetsk.
However, fighting is reported in various parts of eastern Ukraine.
The defense ministry in Kiev says militants attacked government forces in Kramatorsk on Friday. Video released by the ministry shows a tank on flame.
Media report that 4 soldiers were killed.
Pro-Russian supporters say fighting is also taking place in Kramatorsk on Saturday.
