Voters in the Indian Ocean archipelago of the Comoros cast their ballots in an election for a new president Sunday from a crowded field of 25 candidates, with a struggling economy and poor infrastructure high on the agenda. Officials started counting the ballots after polling stations closed, using candlelight and camping lamps in a country that suffers from endemic electricity shortages that paralyse the economy, said an AFP journalist in Moroni. A total of 159,000 voters on Grande Comore island were eligible to vote in the first round of the election, in accordance with electoral rules that stipulate the president is chosen on a rotating basis from one of the archipelago's three main islands.
