NOVOHANNIVKA, Ukraine — Pro-Russia separatists shot down a Ukrainian military transport plane Saturday, killing all 49 crew and troops aboard in a bloody escalation of the conflict in the country's restive east.
It was a bitter setback for the Ukrainian forces, which have struggled to suppress an armed insurgency by foes of the new government. And it came only a week after Ukraine's new president, billionaire candy magnate Petro Poroshenko, spoke about a peace plan in his inaugural address.
Yet the deadliest single incident in the four-month-old conflict suggested the two sides were still far apart in their demands and talk of de-escalating the conflict remained premature.
The loss of the plane "will refocus attention on the fact that Russia does not seem to be doing very much to moderate the insurgency (or) the cross-border resupply of separatists," said Timothy Ash, an analyst at Standard Bank PLC.
The United States, meanwhile, rejected Russia's statements that it was not arming the separatists, saying Russia clearly had sent tanks and rocket launchers to the rebels, making sure the unmarked tanks were of a type not currently being used by Russian forces.
Nine crew and 40 troops were aboard the Il-76 when it went down early Saturday as it approached the airport at Luhansk, the Ukrainian prosecutor general's office said. The Russian-built Il-76 is a four-engine jet used to transport heavy gear and people.
Luhansk is in eastern Ukraine near the border with Russia, an area where separatists have seized government buildings and declared independence after holding disputed referendums. Ukrainian forces still control the Luhansk airport, however.
Defense Ministry spokesman Bohdan Senyk said the rebels used anti-aircraft guns and a heavy machine gun to down the plane, while the prosecutor general's office mentioned an anti-aircraft missile.
The plane's tail section lay with other pieces of scorched wreckage in a field near the village of Novohannivka, 20 kilometers (12 miles) south of Luhansk. An AP reporter saw a dozen or more armed separatists inspecting the crash site.
The death toll Saturday exceeded the 46 who died after a fire and shootings in Odessa on May 2 and the 12 troops who died May 29 when rebels shot down a helicopter near the eastern city of Slovyansk.
