Beijing  -  Recent events have increased the risk of a terrorist attack at this summer's Beijing Olympics, the secretary general of Interpol said Friday.

"An attempted act of terrorism is a real possibility and a real concern that all Olympic host countries have shared in recent years," Ronald Noble said at the opening of the International Conference on Security Cooperation in Beijing.

"Recent Tibet-related protests have introduced significant additional complications to the normal security considerations for a major international event like these Olympics."
