A Gabonese soldier patrols a street in Port Gentil on September 6, 2009 during a visit from the Interior Minister Jean-Francois Ndongou. Violence erupted Thursday when Ali Bongo, 50, was declared the winner of presidential elections to succeed his father Omar Bongo, who ruled this oil-rich West African nation for 41 years until his death in June. Gabon's government threatened Sunday to impose emergency powers to quash unrest in its second city Port-Gentil after three people were killed in post-election violence. Ndongou warned that the government could ask parliament for emergency powers that would impose a virtual lockdown on Port-Gentil, which is already under a dusk-to-dawn curfew.
