Ahmed Ali Abdullah Saleh, a son of the veteran former leader who ruled in Sanaa from 1978 until earlier this year, commands the elite Republican Guards unit of the army.
Organisers of the march, which for security reasons avoided nearing Saleh’s residence guarded by gunmen, called for another demonstration on Friday to demand that Saleh’s family and close aides be purged from the military.
Under a Gulf-brokered transition deal, Saleh stepped down in February after a year-long deadly uprising. But he remains president of his General People’s Congress party, retains loyalty of army elements and owns a television station
