By Paulo Prada and Pedro Fonseca RIO DE JANEIRO (Reuters) - Security is the top focus for the laboratory that will conduct doping exams at the upcoming Olympics in Rio de Janeiro, the lab's director said Friday, amid global scrutiny following the recent scandal surrounding Russian athletes. Citing major breaches that the World Anti-Doping Agency (WADA) described at a Russian laboratory, chemist Francisco Radler said the lab must ensure that cheating, through infiltration by outsiders or other efforts to manipulate testing, is "impossible." In an interview with Reuters outside the new laboratory, a remote five-story building on the island campus of the Federal University of Rio de Janeiro, Radler said a security force of about 50 people, including military police and private guards, will guard the nearly 200 local and international scientists and technicians who will conduct Olympic testing.
Pope Francis on Friday walked alone through the notorious wrought-iron "Arbeit Macht Frei" (Work Sets You Free) gate as he visited the former Nazi death camp Auschwitz-Birkenau. Among them was Helena Dunicz Niwinska, a 101-year-old woman who played the violin in the Auschwitz orchestra, as well as inmates who worked at the camp hospital or who were there as children. Francis lit a candle in front of the death wall before visiting the cell of Polish priest and saint Maximilian Kolbe, who died at Auschwitz after taking the place of a condemned man.
By Amanda Becker PHILADELPHIA (Reuters) - Democrat Hillary Clinton took her newly energized campaign to become America's first woman president on the road on Friday to states in the "Rust Belt" that might decide the fate of the Nov. 8 election. After presenting an upbeat view of the country in her keynote address to the Democratic convention on Thursday night, the former secretary of state launched a campaign tour of Ohio and Pennsylvania, two heartland states hit by the decline in U.S. manufacturing. Clinton is likely to face a tough challenge in such states from Republican nominee Donald Trump, a New York businessman who is trying to win white working-class voters with rhetoric against free trade and illegal immigration.
