UN helicopter gunships have attacked suspected rebel positions in eastern Democratic Republic of Congo, reports said. The two sides have been involved in fierce fighting about 50 km (31 miles) north of the provincial capital, Goma, BBC reported today. 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. According to the BBC, the gunships were dispatched in support of government forces battling the M23 rebel group, in fighting centred around the Rutshuru area, about 50 km north of Goma.
