Ukraine's President Viktor Yanukovych has offered the position of prime minister to an opposition leader, Arseniy Yatsenyuk.
The offer came after talks on Saturday with opposition leaders in a new effort to end the worsening unrest that has spread across the country.
Earlier, protesters in Kiev tried to occupy the energy ministry.
The protests began in November after Ukraine decided not to sign an accord on more co-operation with the EU.
Instead, the government opted to deepen ties with neighbouring Russia.
