Human Rights Watch is accusing the Angolan army of arbitrarily detaining, torturing, and killing civilians in Angola's troubled Cabinda providence.
The New York-based group said Thursday that Angolan army troops frequently beat detainees suspected of being rebel supporters or combatants.
It said soldiers have also been implicated in rape and other sexual violence against civilians, adding that these abuses have continued despite an apparent end to Cabinda's decades-long fight for independence.
Angola's ruling party has denied the charges.
The oil-rich Cabinda province does not share a border with Angola. It is sandwiched between Africa's two Congos, Republic of Congo and the Democratic Republic of Congo, to the north of Angola.
