The head of a human rights group in Congo says three more people have succumbed to their wounds after an attack by rebels in the northeast, raising the death toll to at least 10.

Jean-Paul Ngahangondi said Friday that two people remain missing after the attack overnight Wednesday in the Kasinga-Munzambayi locality about 5 kilometers (3 miles) from Beni. He says a dozen homes and two military camps were burned and food and valuables stolen.

He says the U.N. peacekeeping mission has reinforced its presence in the area.

Congo's military has blamed Allied Democratic Forces rebels. The rebels have been accused of killing more than 700 people since October 2014 in the area.

They are among scores of armed groups that have been present in eastern Congo for years.
