Pro-Russian armed men standb at the entrance to the regional government headquarters in LuhanskMasked gunmen in military fatigues took control of a government building in another Ukrainian town on Wednesday, as pro-Russian separatists tightened their grip on a swathe of the country’s industrial east largely unopposed by police. Local media reports said the gunmen turned up at first light, and were later seen by a Reuters photographer to be controlling entry to the building in the town of almost 300,000 people. They refused to be photographed. The heavily armed men wore the same military uniforms without insignia as other so-called “green men” who have joined pro-Russian protesters with clubs and chains in seizing control of a string of towns across Ukraine’s Donbass coal and steel belt abutting the border with Russia.
