Workers in Kinshasa's Ndolo airport, DR Congo, are putting together the final preparations for Wednesday morning's mass, where more than a million people are expected to attend. A vigil will also be held from Tuesday evening until the arrival of Pope Francis. The pontiff's plane is due to land at 3pm (1400 GMT) in Kinshasa, the capital of Africa's largest Catholic country, where he is expected to be greeted by a jubilant crowd. IMAGES
