The thrill of competition at the Olympics was tempered by tragedy on Saturday, when two American tourists were stabbed. One of the victims, the father-in-law of the U.S. volleyball coach, has died. His wife was also stabbed and her injuries are considered life threatening.
The attacker, a 47-year-old Chinese man, also stabbed the tourists' guide before jumping to his death.
There is no apparent motive.
The attack happened at the Drum Tower, a 150-foot structure in central Beijing that used to tell time during the 13th century. It is now a popular tourist attraction.
A daylight stabbing in a tourist district is rare in China.
