Thousands of Algerian students marched Tuesday through the capital calling for the overthrow of the "system" and trials for members of ousted president Abdelaziz Bouteflika's inner circle.
The rallies came as state media reported that Algeria's richest man has been detained in jail after his arrest as part of a corruption probe and Sunday's arrest of four other business tycoons. Some have close links to Bouteflika's entourage.
