New York Times: “The war in eastern Ukraine, which has been on a low simmer for months, drawing little international attention, has escalated sharply in recent days, according to statements on Tuesday from the Ukrainian and Russian governments. In the deadliest engagement so far this year, four Ukrainian soldiers were killed and another seriously wounded in a battle against Russian-backed separatists in the Donetsk Region of eastern Ukraine, the country’s military said. The soldiers’ deaths, along with a buildup of Russian forces on the border, has seized the attention of senior American officials in Europe and Washington. In the past week, the U.S. military’s European Command raised its watch level from possible crisis to potential imminent crisis – the highest level – in response to the deployment of the additional Russian troops. The exchange of artillery and machine-gun fire in the Donetsk Region was unusual in that it lasted most of a day.”

“Fighting across the so-called Line of Contact, a roughly 250-mile-long barricade of trenches and fortifications, are typically briefer. But it was not the only sign of tensions in a region where Ukrainian and the Russian-backed separatist forces have settled into trenches that have barely moved over the seven years since fighting erupted in 2014. European monitors have spotted new weaponry on the Russian-backed side in recent weeks. Artillery fire has become more frequent. And Russian negotiators have warned of a breakdown in peace talks that have been dragging on for years. On Tuesday, the Kremlin spokesman, Dmitri S. Peskov, acknowledged the recent increase in fighting and said Russia ‘sincerely hoped’ it would not escalate. The fighting, he said, is ‘canceling out the modest achievements made earlier.’ In Ukraine, Parliament on Tuesday approved a statement declaring an ‘escalation’ along the front, essentially acknowledging that a cease-fire negotiated in July had broken down. It pointed to a ‘significant increase in shelling and armed provocations by the armed forces of the Russian Federation.’ The statement called on Western governments to ‘continue and increase international political and economic pressure on Russia,’ something Ukraine has been requesting for years.”
