Speaking before lawmakers in Kinshasa, Tshisekedi said Rwanda was failing to honour the commitments it made in a series of US and Qatar brokered arrangements meant to de-escalate tensions between the DRC, Rwanda, and the M23 rebel movement. Rwanda did not immediately respond to the remarks.
Attempts to implement the peace framework have been overshadowed by renewed violence. Over the weekend, fighters from the Rwanda backed M23 group advanced near the Burundian border and seized the village of Luvungi, according to two residents who shared video footage showing the rebels holding a meeting in the area. Rwanda continues to deny supporting M23.
Local officials reported that some DRC soldiers withdrew from nearby positions and later clashed with Wazalendo community defence groups in the town of Sange. The town was then struck by either bombs or grenades, killing up to 36 people, according to officials and civil society sources. It remained unclear which party fired the ordnance or what type of weapon caused the deadly blast.
A civil society representative circulated photographs showing bodies covered in blood, including women and children in brightly coloured civilian clothing.
The DRC army did not respond to requests for comment, and M23 also declined to comment.
Both countries reaffirmed a US brokered agreement last week and signed additional documents in Washington, but the latest escalation has raised fresh doubts over whether the roadmap can hold.
