União dos Sindicatos Revolucionarios de Angola
União dos Sindicatos Revolucionarios de Angola was an Angolan trade union organization in exile. USRA was founded in Songololo, Congo-Kinshasa in November 1965 by dissidents from LGTA led by Manuel Francisco Bento and another dissident group from UNTA. Dombele had accused UNTA of 'political deviation'. The organization opened an office in Kinshasa in April 1966.
As of 1967, USRA had ceased to exist.
