Gabon's transitional government said Thursday that presidential elections would be held on April 12, a key step to re-establish civilian rule after a coup ended the Bongo dynasty's decades-long reign. "Voting will start at 7:00 am and end at 6:00 pm in line with current laws," government spokesman Seraphin Akure Davain announced after a cabinet meeting. The oil-rich central African country, which had been under the rule of the Bongo family for 55 years, adopted a new constitution in a November referendum. It provided for a maximum of two seven-year presidential terms, no prime minister and no dynastic transfer of power.
