Columns with Russian-backed militants' military hardware have entered Ukraine from the side of the Russian Federation and partly from the occupied town of Rovenky in Luhansk region, according to Ukrainian online newspaper Novosti Donbasa, which cites own sources.
"Three columns with Russian proxies' military hardware are now moving in three directions, heading for the occupied cities of Luhansk, Debaltseve and Donetsk," Novosti Donbasa wrote.
What is more, militants have transported their equipment by rail via the railway station of Shterivka in Luhansk region.
Ukraine's External Intelligence Service has previously announced that the combined Russian-separatist forces planned to conduct a number of large-scale acts of terrors in temporarily occupied territory of Ukraine on Independence Day on August 24.
