In pictures: Fresh Ukraine protests
- Published
Pro-European Union protesters angry at the Ukrainian government's decision not to sign a major trade and association deal with the EU clash again with police in Kiev.
Opposition leader and boxing champion, Vitali Klitschko, who is standing as a candidate in the next presidential elections, has vowed to keep up the protests.
A number of protesters have been detained by police and could face criminal proceedings.
Protesters argue the future of the country should be with western Europe and not Russia - but many Ukrainians still feel closer to Russia.
The EU says the jailed opposition leader, Yulia Tymoshenko, must be freed before Ukraine can sign the co-operation pact with the EU.
Attempts by protesters to enter government buildings are thwarted by police.
Not since the 2004 Orange Revolution - a pro-Western movement - has Ukraine seen protests on this scale.
