Clashes broke out in eastern Congo on Thursday between the military and M23 rebels, a civil society and a rebel source said, a day after the presidents of Congo and Rwanda agreed to de-escalate diplomatic tensions over the insurgency.
The M23, which Congo accuses Rwanda of supporting, began a major offensive in the eastern borderlands at the end of March, seizing an important border post and other towns despite army efforts to stop its advances.
Rwanda denies backing the M23 and has in turn accused Congo of fighting alongside another armed group intent on seizing power in Kigali.
