YAOUNDE, CAMEROON — Cameroonian officials said Monday five people are dead and several hundred are homeless in ongoing conflicts between host communities and people who arrived after being displaced by Boko Haram terrorism in the nation’s border area near Chad and Nigeria. Hundreds of irate host community members set fire to at least 60 government-built houses for internally displaced people in Yala Yalta, military officials said. Three displaced people died, and two host community residents died of injuries while being rushed to a local hospital. Government officials say it was the second burning of houses in the past five days.
