State media in Chad say an attack on the presidential palace left 18 assailants dead and six in custody, with one soldier killed and three wounded. The attack on Wednesday night occurred while Chadian President Mahamat Deby Itno was inside the palace, but authorities said the situation was quickly brought under control. The attack occurred about a week after the African nation held parliamentary elections that were supposed to help restore democracy, but the main opposition party boycotted the polls. Results have not been announced, and analysts have said they expect the election to help Deby Itno consolidate his grip on power.
