KIEV, Ukraine (AP) — Ukraine's military and Russia-backed separatist rebels are accusing each other of continuing to mount attacks a week after a cease-fire was called.

Ukrainian security spokesman Col. Andriy Lysenko said Saturday that one serviceman was killed and 40 wounded in attacks over the past day. He did not state a total number of attacks, but said there were 10 mortar attacks on Ukrainian forces in the village of Shyrokyne on the fringes of the strategic port city of Mariupol.

Lysenko said rebels continued to move equipment toward Mariupol. Concerns persist that rebels aim to seize the city which would aid establishing a land corridor between mainland Russia and the Russia-annexed Crimea peninsula.

The rebels claimed Ukrainian forces launched 15 shelling attacks overnight, including on parts of Donetsk, the largest rebel-controlled city.
