Braving the night chill beyond Ukraine’s capital, protesters have invaded regional government headquarters in several western and central cities.
In Lviv, they set up makeshift barricades to prevent authorities taking back the building.
Having forced their way inside, demonstrators got governor Oleg Salo, who was appointed by President Yanukovych, to say he would step down.
But once allowed to leave the premises, he retracted his resignation, insisting he had only signed his name to it under duress.
Demonstrators say they plan to stay put permanently.
While some stand guard outside, others are preparing hot drinks and sandwiches. It is the first step in their plan to create a People’s Council to replace the governor.
Mykhaylo Dubyak, our correspondent in Lviv, confirmed protesters’ desire to stay all night, saying they have brought mattresses and want to rule the Lviv region themselves.
