KIEV, Ukraine (AP) — An anti-corruption agency established in Ukraine two years ago was expected to be the driving force that would uproot the endemic graft that depleted the nation's resources and worried its Western allies. But the National Anti-Corruption Bureau of Ukraine instead has come under fire from allies of President Petro Poroshenko who are trying to curtail its operations and authority. NABU chief Artem Sytnik told The Associated Press in a weekend interview that fear is behind the recent attempts by political and business elites to weaken the agency that was supposed to be a visible symbol of reform in Ukraine. "The old and new elites are quite scared" after realizing "there are no untouchables anymore," Sytnik said.
