Congo’s government is questioning Apple about the tech company’s knowledge of “blood minerals” from a conflict zone in the African country that could be smuggled into supply chains. A group of international lawyers representing Congo said Thursday, April 25, 2024, that it sent letters to Apple’s CEO Tim Cook and its French subsidiary this week raising concerns about human rights violations involving the minerals extracted from mines in the country’s war-torn east.
