Ukraine celebrates Flag Day. Festivities are held though out the country. Ukrainian President Petro Poroshenko officially hoisted the flag together with Maria Rybak, of Volodymyr Rybak’s daughter, killed by militants in Horlivka in 2014.
Volodymyr Rybak was abducted by separatists on 17 April 2014 after trying to raise the flag of Ukraine on Horlivka's town council building instead of the separatist’s flag of so-called Donetsk People’s Republic. His life was the forfeit of this.
