The Democratic Republic of Congo has filed criminal complaints in France and Belgium against subsidiaries of the tech giant Apple, accusing it of using conflict minerals.
Acting on behalf of the Congolese government, lawyers have argued that Apple is complicit in crimes committed by armed groups that control some of the mines in the east of DR Congo.
Apple has said it "strongly disputes" the claims and that it is "deeply committed to responsible sourcing" of minerals.
The authorities in France and Belgium will now look at whether there is enough evidence to take the legal action further.
