For whom did President Obama deliver the address?

President Obama has hailed Nelson Mandela as one of the giants of history in an address at the former South African president’ s memorial service, comparing Mandela to Mohandas Gandhi, Abraham Lincoln and Martin Luther King. Mr. Ohama called him the last great liberator of the 20th century. He urged the crowd of world leaders, celebrities, and tens of thousands of South Africans to embrace his message of peace. But Mr. Obama had a tough message too, questioning whether today’ s leaders were living up to Nelson Mandela’ s integrity and commitment to justice and peace.

Experts investigating the Spanish train crash which killed 79 people last week have told a court that data recorders fitted to the high-speed train show that it was traveling at 153 km/h, almost twice the speed limit for that section of track when the train derailed. But the court also says the driver Francisco Jose Garzon was talking on the phone to an official of the state railway company Renfe when his train jumped the rails and he was apparently consulting a piece of paper at the time. The court inquiry is still in its early stages but these suggestions will add to a sense of outrage which is mingled with grief across Spain.
