A soldier shot dead two election workers in eastern Congo early on Monday after historic elections had ended, provoking a riot in which 43 polling stations were destroyed, the United Nations said. Leocadio Salmeron, U.N. spokesman in Bunia, the capital of war-scarred Ituri district, said the Congolese army sergeant appeared to be drunk. He was arrested but angry people burned the polling stations, ballots and result sheets in Fataki, north of Bunia, Reuters reported.
