World leaders vowed Monday to save mankind from catastrophic climate change as an historic summit opened with the "hope of all humanity" laid on their shoulders, but fault lines quickly emerged. The heads of more than 150 nations -- a record -- kicked off 12 days of talks in search of an elusive pact that would shift the world economy away from its heavy use of fossil fuels blamed for global warming. "Never have the stakes of an international meeting been so high, because it concerns the future of the planet, the future of life," French President Francois Hollande said in an opening speech.
Pope Francis on Monday said Christians and Muslims were "brothers" and urged them to reject hatred and violence as he visited a mosque in the Central African Republic's capital which has been ravaged by sectarian conflict. On the last leg of a three-nation tour of Africa, the leader of the world's 1.2 billion Catholic visited a flashpoint Muslim neighbourhood in Bangui on what was the most dangerous part of his 24-hour visit. As his vehicle passed, many waving Vatican flags and dressed in long traditional robes, ran down the road after it, an AFP correspondent said.
