Pope Francis, 87, welcomes journalists and staff on board the papal plane as he flies to Indonesia on the first leg of an ambitious four-nation tour, with inter-faith ties set to dominate his visit to the world's largest Muslim country. The pontiff left Rome on Monday afternoon and landed in Jakarta on Tuesday morning, the first stop in a 12-day voyage that will also take in Papua New Guinea, East Timor and Singapore. Covering some 32,000 kilometres (almost 20,000 miles), the tour will test the Argentine's increasingly fragile health, but he often seems energised by being among his flock. IMAGES AND SOUNDBITES
