The JRS-backed Radio Kwizera has donated 50 solar powered free-play radio sets to schools in the refugee camps of Ngara and Biharamulo districts of Tanzania, the Catholic NGO Jesuit Refugee Services (JRS) reported on Friday. Forty six of the radios would be used by primary schools in the camps of Lukole, Lumasi and Kitali to monitor education programmes produced and broadcast by Radio Kwizera, it said.
