Rebels have set up a de facto administration in eastern Democratic Republic of Congo, UN peacekeeping chief Herve Ladsous said as the Security Council urged a political solution to the crisis rather than applying sanctions. Ladsous briefed the 15-member Security Council after his recent visit to Congo, or the DRC, and Rwanda, which has been accused by Kinshasa and UN experts of supporting the M23 rebel group. Kigali has repeatedly denied any involvement in the crisis.
