Russian and Ukraine Troops battle in South

Fighting between the Ukrainian military and what Ukrainian and Western officials say are Russian troops worsened early Thursday, prompting fears in Ukraine that a Russian invasion of their territory has begun. Ukrainian officials say Ukrainian troops are continuing to battle combined Russian and separatist forces on a new southern front around the border town of Novoazovsk, east of Crimea on the Sea of Azov. A military spokesman also said Russian troops are increasing surveillance from northern Crimea, the autonomous Ukrainian peninsula annexed by Moscow in March. As firefights and shelling continued all day Wednesday and into the night, there were differing reports on whether Novoazovsk, a previously quiet border town, had fallen to Russian-backed separatists.
