Former President Kumba Yala said on Sunday he had won presidential elections in the troubled and impoverished West African country of Guinea-Bissau, disputing electoral commission results that put him in third place. Final results on Saturday showed no candidate won a majority, meaning the two frontrunners -- both also former presidents -- would contest a run-off vote in a nation torn by uprisings and war since independence from Portugal in 1974, Reuters reported. The run-off will pit first-placed Malam Bacai Sanha of the main PAIGC party against former military ruler Joao Bernardo Vieira, known as "Nino". It will be held from July 17-24. Yala, ousted two years ago in a bloodless military coup, said he was waiting for reports from his campaign director before deciding his next move over the poll, which was designed to restore democracy. "One must not sacrifice lives for personal ambition," he said, just days after three people were killed during protests by his supporters. --More 2318 Local Time 2018 GMT
