Ukraine conflict: Petro Poroshenko brands rebel polls 'a farce'

Ukraine's president is to chair a crisis meeting of his security chiefs, following elections in rebel-held areas which Kiev describes as a "farce".

In a TV address, Petro Poroshenko said Sunday's polls in parts of the eastern Donetsk and Luhansk regions could derail the "entire peace process".

Two pro-Russian leaders were declared the winners of the polls and are expected to be sworn on Tuesday.
