DR Congo rebels 'aim to take Goma'

Fighting has continued for a third day between rebel forces and the Congolese Army.
The two sides have been involved in fierce battles 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.
