Ukraine could risk creating a civil war if its doesn't get its "house in order", the European Union's justice chief told CNBC, as violent protests have gripped Kiev for two months.
The comments come after the first deaths in the troubles were reported Wednesday and as a fragile truce had begun between protesters and security forces.
"I am very worried about what is happening in the Ukraine in this moment because that goes in direction of a civil war, the worse thing which can happen to a country," EU vice president and justice commissioner Vivian Reding, told CNBC in a TV interview.
"I hope that common sense comes back and that the two sides manage to come together to create a common country in the interest of all Ukrainian people."

This Friday, Ukraine's President Viktor Yanukovich said he would reshuffle the government next week, according to the Interfax news agency.
The clashes began in November after the Ukrainian president Viktor Yanukovych backed down from a deal with the EU that would have brought them closer to integration with the 28-nation bloc.
In the following weeks, he signed a deal with Russia that further strained tensions with the EU and angered the population.
The protests escalated when the Ukrainian government passed a draconian law last week to prevent protests on the street and restricted access to some websites.
