Vast crowds of Ugandans greeted Pope Francis on Saturday as he honoured Christians martyred for the faith on the second leg of a landmark trip to Africa, which he dubbed "the continent of hope".
The 78-year-old pontiff received a rapturous welcome as he arrived at a shrine to the martyrs at Namugongo, just outside the capital Kampala, where some 45 Christians were executed in 1886 for refusing to recant their faith.
