Hundreds of thousands of protesters demanding radical change marched through Algiers for a seventh successive Friday, Reuters reported. Algeria’s spy chief was reportedly fired on the same day in a further sign of high-level turmoil after the veteran president, Abdelaziz Bouteflika, resigned on Tuesday. Retired army general Athmane Tartag was a close ally of President Bouteflika. Tartag’s departure was reported by the private Ennahar TV, and two political sources confirmed that he had been sacked. No clear successor to Bouteflika has yet emerged. Protesters have made it clear they will reject any candidate with ties to the old guard.
