Ukrainian forces killed up to five pro-Moscow rebels on Thursday as they closed in on the separatists' military stronghold in the east and Russia launched army drills near the border in response, raising fears its troops would go in.

But they have shown no signs of doing so and on Thursday, the Ukrainian Interior Ministry said its forces backed by the army had removed three checkpoints manned by armed groups in the separatist-controlled city of Slaviansk.
