(Reuters) - One Ukrainian serviceman was killed and seven servicemen were wounded in attacks by pro-Russian separatists in the past 24 hours in eastern Ukraine, Ukraine's military said on Sunday.

Spokeman Oleksander Motuzyanyk said the separatists had stepped up their attacks against government forces in violation of a February ceasefire and were using large-caliber artillery which both sides are committed to pulling back from the conflict area.
