Bedjo Untung, 73, who is now head of the Indonesian Institute for the Study of the 1965-66 Massacre, demanded a full apology and explanation from the British authorities.

Just 17, Bedjo had joined a student organization with ‘anti-imperialist and socialist-leading’ ideology, and for that reason, he and his father were imprisoned.

Although some decades passed, it was just a few days ago that a secret report by the US Central Intelligence Agency (CIA) was declassified. It described the massacre as ‘one of the worst mass murders of the 20th century.’

Last week, The Observer published evidence that Britain played a role in inciting the killings.

It is estimated that at least 500,000 people were killed between 1965 and 1966 by Indonesia’s army, militias and vigilantes.
