The Ukraine provisional government was unable to deliver on its ultimatum to pro-Russian separatists in seven eastern cities to hand over their weapons and evacuate public buildings by early Sunday – or face armed force to remove them.  Instead, they captured the public buildings of an eighth town, Horlivka near Donetsk. Kiev reacted by again suggesting a national referendum. DEBKAfile adds: There are signs that operationally-capable Ukrainian military units have stopped taking orders from the provisional government.
