Ukraine Truce Vanishes as Government Says 200 Rebels Dead

Ukraine’s military said it killed as many as 200 rebels in an attack in Donetsk, inflicting the biggest blow from either side in the conflict in more than two months and removing pretense that a Sept. 5 truce is holding.

Accusing Russia of sending dozens of tanks and other military vehicles across its border yesterday into separatist-held areas in eastern Ukraine, military spokesman Andriy Lysenko said Ukraine’s army was preparing for “an adequate reaction.” Lysenko said artillery strikes had killed the rebels and destroyed tanks and other armored vehicles after Ukrainian forces took fire at the Donetsk airport, where they have faced almost daily attacks.
