Rebel troops are under pressure in eastern Democratic Republic of Congo, following an offensive by UN-backed government forces, the BBC news reported. The two sides have been involved in fierce fighting about 50 km (31 miles) north of the provincial capital, Goma. The latest unrest began in April, with the UN and DR Congo government accusing neighbouring Rwanda of backing the rebels - a charge it denies. More than 200,000 people in the region have been displaced by the conflict. The fighting is centred around the Rutshuru area, about 50 km north of Goma, according to BBC. This could mean government forces, supported by UN peacekeepers, have pushed the M23 rebels back.
