DONETSK, Ukraine, Shawwal 2, 1436, Jul 18, 2015, SPA -- Ukraine and pro-Russian rebels accused each other on Saturday of shelling residential areas despite a ceasefire, reporting four civilians and one soldier killed following a week of the deadliest fighting in over a month, Reuters reported. Separatists said one man was killed by shelling from Ukrainian forces in central Donetsk. A Reuters witness reported seeing the body of man in a burning building, though it was unclear if it was the same person. More than 6,500 people have been killed since the conflict broke out in eastern Ukraine in April last year. Attacks have lessened since a peace agreement was brokered in Minsk, Belarus, five months ago, but both sides accuse each other of violations. "The vast majority of shelling and armed attacks by the rebels take place at night to avoid attracting the attention of international observers," Ukrainian military spokesman Andriy Lysenko said. --SPA 03:16 LOCAL TIME 00:16 GMT www.spa.gov.sa/w
