Police in eastern Democratic Republic of Congo arrested at least four people on Saturday who were protesting the failure of government and U.N. peacekeeping forces to prevent repeated massacres, the United Nations said.
Over 500 people have been killed in dozens of raids near the northeastern town of Beni since October 2014. The government and United Nations have blamed almost all of the attacks on a Ugandan Islamist rebel group, though analysts say others, including some Congolese army soldiers, are also involved.
