Three Ukrainian servicemen have been killed and 14 wounded in the past 24 hours in fighting in separatist eastern territories despite a ceasefire, the Ukrainian military said on Thursday. Ukraine and separatists have accused each other of increasing attacks in recent weeks, prompting international monitors to warn of the threat of a bigger flare-up. “Clashes aren’t getting any less frequent and in certain parts they are turning into full-scale military operations,” Ukrainian military spokesman Andriy Lysenko said. On Wednesday Russia and Germany, who were involved in brokering the Minsk ceasefire deal in February, called for an immediate cessation of hostilities. Separatist officials accused Ukrainian forces of shelling and firing from tanks at rebel territory overnight and expressed disappointment in the pace of the peace process, rebel press service DAN reported.
