KIEV, July 1 (Reuters) - One Ukrainian serviceman was killed and ten others were wounded in separatist attacks in the troubled east of Ukraine in the 24 hours up to mid-day on Wednesday, the Ukrainian military said.
"The situation in the Donetsk region remains the most difficult and it has not undergone major changes - separatists are using tanks and mortars," Ukrainian military spokesman Andriy Lysenko said in a televised briefing.
