A rebel alliance claimed the capture of the biggest city in the Democratic Republic of Congo’s mineral-rich eastern region this week, pushing back against resistance from government troops backed by regional and UN intervention forces.

Rwanda-backed rebels claimed on Monday they captured eastern Congo’s strategic city of Goma, the hub of a region containing trillions of dollars in mineral wealth that remains largely untapped.

Fierce fighting rages on in the eastern Democratic Republic of Congo city of Goma, as rebels and the army exchange fire. "All we can hear [are] gunshots around the city," one Goma resident, who has been trapped in his house since the weekend, told the BBC.
