KIEV, Sha'ban 27, 1436, June 14, 2015, SPA -- A Ukrainian serviceman was killed and 21 were wounded in separatist attacks in the past 24 hours, the Ukrainian military said on Sunday, as both sides accused the other of intensifying attacks despite a four-month-old ceasefire deal, Reuters reported. The truce brokered by the leaders of Ukraine, Russia, Germany and France in Minsk, Belarus, has stemmed large-scale fighting but skirmishes claim lives almost daily on both sides. International monitors have warned of the threat of a bigger flare-up. "In the past 24 hours the number of ceasefire violations by illegal military groups has risen," Ukrainian military spokesman Oleksander Motuzyanyk said at a briefing at midday. Two civilians were wounded in shelling of government-held Avdiyivka, he said, describing attacks on the nearby town of Horlivka, the airport of rebel-held Donetsk and the town of Maryinka as being the most intense. Senior separatist commander Eduard Basurin said rebels had recorded 185 ceasefire violations from the Ukrainian side in the past 24 hours, including tank fire and shelling by weapons banned under the Minsk agreements, rebel press service DAN reported. Three rebel fighters and one civilian woman had been wounded, he said. --SPA 14:00 LOCAL TIME 11:00 GMT www.spa.gov.sa/w
