In Chad, Mahamat Idriss Déby, the son of late President Idriss Déby, has been named interim head of state by a military council after his father died, reportedly while visiting frontline soldiers as they battled a rebel advance in the north of the country. The army has also enacted a nationwide curfew and announced Chad’s land and air borders will be shut down. Rebel forces threatened to move toward the capital, prompting fears of further unrest. Idriss Déby had been in power for over 30 years and was just announced the winner of a recent presidential election before his death. Rights groups are calling for a quick transition to democratic civilian rule and an accounting of human rights abuses under Déby’s reign.
