Washington concerned about uptick in ceasefire violations in eastern Ukraine

"We are disturbed by an uptick in ceasefire violations in eastern Ukraine over the past two weeks," Kirby said. He stressed that the Russian-separatist forces had repeatedly attacked Ukrainian forces with small arms, grenade launchers, anti-aircraft weapons, and high-caliber machine guns. According to Kirby, these violations endanger the ceasefire and the Minsk Agreements implementation, being the right path to restore peace as the United States has said before. "We call on Russia and the separatists to end the violence and to live up to their Minsk commitments," the spokesperson for the U.S. Department of State said.
