Bertrand Bisimwa, the president of the M23 rebel group in eastern DR Congo, has accused government forces of taking over positions ceded to the East African Community (EAC) regional force as a buffer zone. The government forces and their allied militias, like FDLR, Nyatura and Mai Mai, occupied the locality of Mushaki on Saturday, May 13, according to Bisimwa.

It is imperative that the Kinshasa regime respect its own commitments,” Bisimwa said.

Mushaki is supposed to be under the control of the Burundian contingent of the regional force. Kinshasa government accuses the regional force of siding with the rebels, which has led to disagreements that may see the force exit in June.

The M23 also said the government forces were responsible for killing 17 people in Kizimba, in Masisi territory.
