China: Tibet protest unfurled

BEIJING — Foreign activists scaled a landmark building in Beijing early today to unfurl a "Free Tibet" banner over the top of an Olympic Games billboard, in the latest unauthorized protest during the Games.

Students for a Free Tibet said five people — three Americans, a Briton and a Canadian — were detained by police after hanging the banner from the new headquarters of state-owned China Central Television, which is still under construction.

Television footage by Britain's Sky News showed the activists, draped in Tibetan nationalist flags and wearing helmets, dangling from ropes as they hung the black-and-white banner about 20 feet off the ground. Police quickly took the banner down.

Argentina: Child deaths probed

BUENOS AIRES — Argentine authorities are investigating a possible link between the deaths of 14 children and an experimental vaccine they were taking in a clinical trial.

Argentina's food and drug agency has told The Associated Press that it is checking to see if the deaths are linked to the Synflorix vaccine, which is aimed at fighting pneumonia, ear infections and several other pneumococcal diseases.

The vaccine is manufactured by the Britain-based GlaxoSmithKline PLC.

Sarah Alspach, a spokeswoman for the company in the U.S., says the company is not blaming the deaths on the vaccine.
