Protests are intensifying in Kyiv over the Ukrainian government's decision not to enter into an EU agreement, and to keep former opposition leader Yulia Tymoshenko behind bars.

Tymoshenko's daughter Eugenia says the future of Ukraine is largely bound by her mother's imprisonment as an act of political retribution, and she has called on her mother's supporters to continue their campaign demanding her release.

Recent demonstrations have brought as many as 300,000 people to the streets of Kyiv, in the largest outpouring of public anger since the 2004 Orange Revolution.

Ukrainian President Viktor Yanukovych has sought to quell public anger by moving to renew talks with Brussels. The government appears to recognize that police violence against protesters may have galvanized long-brewing frustrations rather than stifle demonstrations.

Eugenia Tymoshenko says she believes the protest movement could lead to a change in government in the country if it's supported by "democratic forces of the West."
