介绍： BBC News. Hello, I'm Gareth Barlow. Guinea Bissau is holding a presidential election after weeks of violent protests in an alleged coup attempt. President Jose Mario Vaz, the first democratically-elected president to serve his full term in office, is seeking reelection. He's facing eleven other candidates, including the former Prime Minister Domingos Simoes Pereira. Tensions between Present Vaz and the ruling party have been high. In recent weeks, the regional bloc ECOWAS has warned of the threat of civil war.

Pope Francis has made an impassioned appeal for the abolition of nuclear weapons. The pontiff delivered his message in the Japanese city of Nagasaki which was hit by an American atomic bomb in August 1945. Ben Lowings reports. Hundreds of people gathered in the pouring rain to hear the Pope. He spoke next to a photograph taken after the attack which shows the young boy carrying his dead baby brother on his back. The Pope said nuclear weapons were not the answer to a desire for security, peace and stability.
