A large crowd of pro-Russian separatists has stormed the regional administration's headquarters in the eastern Ukrainian city of Luhansk.

A few dozen men, some reportedly armed with metal bars, smashed windows and doors to break into the building.

Activists shouting "Referendum Russia" later flew a Russian flag over it.
