Fighting in Ukraine persists in day before cease-fire is to take effect

Ukrainian military vehicles travel on the road between the towns of Dabeltseve and Artemivsk, Ukraine, Saturday, Feb. 14, 2015. The fighting between Russia-backed separatists and Ukrainian government forces has continued despite the agreement reached by leaders of Russia, Ukraine, Germany and France in the Belarusian capital of Minsk on Thursday. Much of the fighting had taken place near Debaltseve, a key transport hub that has been hotly contested in recent days. The leaders agreed to implement a cease-fire, set to take effect on Sunday, at one minute after midnight. (AP Photo/Petr David Josek) (The Associated Press)
