Unidentified gunmen have killed at least 14 persons, including two health workers, in the eastern part of Democratic Republic of Congo where militia violence has hampered efforts to contain an Ebola outbreak. It is unclear which group carried out the attack. The Allied Democratic Forces, a Ugandan Islamist group active in eastern Congo, has clashed with Congolese troops in Beni in recent weeks, while Mai Mai militiamen, comprising a number of armed bands that originally formed to resist Rwandan invasions in the 90’s, are also present in the region.

Sustained violence and attacks by rebel have disrupted treatment, burials and vaccination programmes in recent weeks.
