KIEV, Sha'ban 28, 1436, Jun 15, 2015, SPA -- Two Ukrainian soldiers have been killed and twenty wounded in the past 24 hours, describing near-constant shelling by pro-Russian rebels in certain parts of separatist eastern territories, Reuters the Ukrainian military as saying on Monday. The ceasefire brokered in Minsk, Belarus, four months ago 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. "The situation in the conflict zone is deteriorating. At key parts of the frontline heavy weapons continue to shell our positions almost incessantly," Ukrainian military spokesman Andriy Lysenko said in a televised briefing. He accused separatists of opening fire in areas that had previously been relatively peaceful and said the fighting showed signs of spreading further. --SPA 13:59 LOCAL TIME 10:59 GMT www.spa.gov.sa/w
