At least 43 illegal miners died when part of a copper mine collapsed in southeastern DR Congo, a Congolese official said on Friday.
Details of the exact toll were still unclear after two galleries caved on Thursday in at a mine in the Kolwezi area operated by Kamoto Copper Company (KCC), a subsidiary of the Swiss company Glencore.
Glencore had put the number of fatalities at 19 but noted in a statement that there could be "possible further unconfirmed fatalities".
Richard Muyej, governor of the Lualaba province, on Friday told a press conference that 43 miners had died in the accident. A day earlier he had put the toll at 36.
But the Red Cross and some civil groups put the number of fatalities even higher, at between 60 and 80 dead.
