Residents of a battle-scarred slum once controlled by Jamaica's biggest underworld boss rallied on Wednesday to demand accountability and justice for a deadly 2010 raid into their community.
Around 100 demonstrators marched to Prime Minister Portia Simpson Miller's offices.
A handful of organisers and residents delivered a petition calling for an international inquiry into the raid.
Most were from Tivoli Gardens, a public housing complex in West Kingston where at least 73 civilians were killed when security forces raided it during a state of emergency.
Organiser Lloyd D'Aguilar of the Tivoli Committee and the Campaign for Social and Economic Justice said the demonstrators wanted a response within 30 days.
Lawyer Hannah Harris-Barrington said she hoped to involve the United Nations and international courts because of "a major cover-up" being perpetrated in Jamaica.
"People are dead and missing," she told the rally.
"We need international attention now because otherwise this is going to happen again."
Attacks such as yesterday's horrific murder in Woolwich didn't happen before the 'war on terror.' It's time we recognised the consequences of the conflicts we've unleashed
