An aid convoy on Monday reached Bangui, the capital of the Central African Republic, after a 50-day blockade by rebels who had cut off the city's lifeline, the UN said. "Fourteen trucks, nine of them from the UN's World Food Programme" arrived, said Lieutenant Colonel Abdoulaziz Fall, spokesman for the MINUSCA peacekeeping mission. Armed groups launched an offensive on the capital on December 19, cutting off a key highway that left more than 1,500 trucks stranded on the border with neighbouring Cameroon. clt-gir/sva/ri/kjl
