M23, a rebel group backed by Rwanda, killed at least 140 people in July in the Democratic Republic of Congo, Human Rights Watch said. Most victims are Hutu.

Despite a peace process, attacks were carried out in more than a dozen villages last month, Human Rights Watch says.

In March, Qatar’s Emir Sheikh Tamim bin Hamad Al Thani in Doha hosted a meeting between Congolese President Felix Tshisekedi and his Rwandan counterpart Paul Kagame, whereafter both leaders called for a ceasefire. Since then, subsequent talks have been held with the DRC and the M23.
