BEIJING — Team officials and state media said a knife-wielding Chinese man attacked two relatives of a coach for the U.S. Olympic men's volleyball team at a tourist site in Beijing.

One of the victims was killed, and one was injured in the attack on the first day of the Olympics Saturday. The man then committed suicide by throwing himself from the second story of the site, the 13th century Drum Tower three miles from the main Olympics site.

The brutal attack shortly after midday was all the more shocking because of the rarity of violent crime in tightly controlled China, which has ramped up security measures even more for the Olympics.
