President Viktor Yanukovych, elected in 2010, appears to be gone from the capital, though it is unclear if he plans to resign. The wave of unrest in Ukraine began in November, when Yanukovych scrapped a European Union trade deal and turned toward Russia. Part of the deal was to release his political opponent, former Prime Minister Yulia Tymoshenko.

Yulia Tymoshenko lost the 2010 presidential election to Yanukovych. The following year, she was sentenced to seven years in prison after being convicted of abuse of authority over a natural gas deal negotiated with Russia, a punishment that the U.S. and Europe sees as politically motivated. Tymoshenko was freed from prison on Saturday, February 22, according to the press officer for her political party. Tymoshenko is seen here at her trial in 2011.
