Congo's army and Rwandan-backed rebels are reinforcing military positions and blaming each other for flouting peace accords in an escalation that experts say risks reigniting the simmering conflict, which US President Donald Trump claims to have ended.
The M23 rebels seized two major cities in eastern Democratic Republic of Congo in January and February, posing the biggest threat to the government in Kinshasa in two decades. The offensive raised fears of a return to regional war as neighbouring armies took sides.
