Ukraine President Petro Poroshenko warned Tuesday that he would consider scrapping the conditions of a September truce with pro-Russian separatists, in the wake of what he referred to as "illegal" elections in the country's east, dpa reported. The disputed vote was held on Sunday in the Donbass region that includes Donetsk and Luhansk. For months the area has been beset by violent conflict between pro-Russian separatists and Ukrainian government forces. A ceasefire protocol signed by the government and militants in early September established special conditions for the region, which Poroshenko threatened to repeal Tuesday during a television address prior to an emergency meeting with his security chiefs.
