Congo's mining heartland a volatile "powder keg" - lawmaker

KINSHASA (Reuters) - Growing unrest in Democratic Republic of Congo's copper-rich Katanga province risks scaring off investors and derailing its thriving mining sector, said the lawmaker heading an inquiry into a rebel attack on the provincial capital last month.

Katanga, in the country's south, has been seen as insulated from the violent unrest that much of the rest of Congo. Billions of dollars have poured into the province to develop mining projects aiming to tap its underexploited mineral wealth.
