SANAA, Yemen: Tens of thousands of Yemenis took to the streets of the capital Sanaa demanding the prosecution of Ali Abdullah Saleh, the longtime autocratic leader who stepped down in February after a year-long uprising.
 
Protesters raised banners Friday reading, "The trial is coming." Witnesses say demonstrators marched in other Yemeni cities as well.
 
Saleh signed a power transfer deal that gave him immunity from prosecution in return for leaving office.
 
However, his public appearance earlier this week in a celebration at the headquarters of his ruling party, which he still heads, sparked public anger and renewed calls for his prosecution over the deaths of protesters and over corruption. His opponents say that he is using his allies and family members in key positions in the security forces to stir unrest.
