Former Ukrainian President Petro Poroshenko, accused of treason by financing Russian-backed self-proclaimed republics in eastern Ukraine in 2014-15, speaks during a rally of his supporters outside the Kiev Court of Appeal, in Kiev, Ukraine. The court says it could not begin consideration of prosecutors' appeal against the decision not to arrest former Ukrainian President Petro Poroshenko on Friday as it had not been provided with case materials. A new session of the court will take place on February 11.
