By Joe Bavier and Philip Pullella BANGUI (Reuters) - Pope Francis ventured into one of the world's most dangerous neighborhoods on Monday to implore Christians and Muslims to end a spiral of hate, vendetta and bloodshed that has killed thousands over the past three years and divided a nation. Ending his three-nation Africa tour under intense security, Francis passed through a no-man's zone to enter PK5, a district where most Muslims who have not fled Central African Republic's capital Bangui have now sought refuge. A heavy deployment of United Nations peacekeepers with rifles and bullet-proof vests was present throughout PK5 and armored vehicles mounted with machine guns were positioned along the route of Pope Francis' motorcade.
World leaders opened a historic summit in the French capital on Monday with "the hope of all of humanity" laid on their shoulders as they sought a deal to tame calamitous climate change. The heads of more than 150 nations kicked off 12 days of talks in search of an elusive pact that would indirectly restructure the world economy, weaning it off fossil fuels that stoke global warming.
