Human-rights groups are turning to Canada's highest court in their effort to sue a Canadian mining company on behalf of the victims of a massacre in Congo. The Canadian Association Against Impunity, a coalition of human rights groups and non-governmental organizations, filed a last-ditch plea to the Supreme Court of Canada on Monday. The groups allege that Anvil Mining Limited provided logistical support to the Congolese military who raped and murdered people as it crushed a rebel uprising in 2004, killing as many as 100 people in the port city of Kilwa…"We've been fighting for years and what we want is justice," Dickay Kunda said Sunday in a phone interview from Congo. "Our wish is to have Canada help us get justice."…Anvil Mining [now owned by Minmetals Resources Ltd., part of China Minmetals]…has denied any culpability in the Kilwa incidents and said logistical support was requested by authorities
