Ukraine's Prime Minister Arseniy Yatsenyuk has blamed the country's security services for failing to halt deadly violence in the southern port city of Odessa.
Mr Yatsenyuk pledged to hold a "full, comprehensive and independent investigation" after at least 46 people - mostly pro-Russian separatists - died in a fire at the centre of the clashes on Friday.

I personally blame the security service and law enforcement office for doing nothing to stop this crackdown.
These security forces are inefficient and they violated the law.
The prosecutor's office is to investigate everyone - starting with the chief of police, his deputies and every single police officer.
