KIEV (AFP) - Ukrainian President Petro Poroshenko on Monday (April 4) denied any wrongdoing after documents leaked from a Panama law firm showed him holding three offshore accounts that could be used as tax havens.

"I may be the first top official in Ukraine who treats declaring assets, paying taxes and conflict of interest issues profoundly and seriously, in full compliance with the Ukrainian and international private law," Poroshenko said in a statement issued on Facebook.
