In the latest sign of ongoing geopolitical strife, Ukrainian forces killed up to five pro-Moscow rebels and Russia launched army drills near the border in response, raising fears its troops would invade. Separately, local police said seven people were injured overnight at a pro-Ukrainian checkpoint near the Black Sea port of Odessa when an explosive device blew up.
