Local elections cancelled in key Ukraine city, parties trade accusations of foul play
Local elections in Ukraine's port city of Mariupol were called off on Sunday, prompting the ruling party of President Petro Poroshenko and the pro-Russian Opposition Party to blame each other for alleged irregularities in the vote.
Mariupol, a city of around 500,000, lies on the coast between the Crimean peninsula, annexed by Russia from Ukraine last year, and separatist-held eastern territory, where a ceasefire between the pro-Russian rebels and Ukrainian forces has largely held since September.
