AlQa'dah 2, 1436, Aug 17, 2015, SPA -- Fighting flared between Ukrainian government forces and Russian-backed separatists in two separate parts of eastern Ukraine overnight with several civilians killed by shelling, Reuters quoted Ukrainian police and separatist sources as saying on Monday. The clashes, near Mariupol in the southeast and at Gorlivka, a rebel-held town, formed part of an upsurge in violence which put further strain on a fragile ceasefire between the two sides. Regional police in Mariupol, a port city on the Sea of Azov, said at least one man and a young woman were killed when rebels shelled the town of Sartan, about 20 km (12 miles) away on Sunday. Several people, including a 10-year-old girl, were taken to hospital with wounds.
