Ukraine unrest: Barricades erected in Lviv

Protesters in Ukraine's capital Kiev have been erecting new barricades after crisis talks between the opposition and President Viktor Yanukovych stalled.

Anti-government protesters have also occupied regional administration buildings in six regions in western Ukraine.

In Lviv, barricades have been erected and the governor Oleg Salo was forced to resign.
