At least 52 people have been killed in a series of attacks in eastern Congo, authorities reported yesterday.
The region, long troubled by conflict, witnessed a sharp escalation over the weekend as government forces and rebels exchanged accusations over responsibility for the violence.
The renewed fighting in Goma, the largest city in eastern Congo and now under the control of the M23 rebel movement, marks the most serious threat to ongoing peace efforts.
The conflict has raised fresh fears of a wider regional war.
Tensions between the Congolese government and M23 rebels have been building for months. In January, the rebels made significant advances, capturing the strategic city of Goma and intensifying the decades-old conflict.
