Survivors of Sept. 11 (search) and other terrorist attacks will meet 14 heads of state in New York for an anti-terrorism summit, Norway's prime minister said Wednesday.

The Sept. 22 summit is the brainchild of Norwegian Prime Minister Kjell Mange Bondevik (search) and Elie Wiesel (search), a Nobel Peace Prize winner. It will coincide with the opening of the U.N. General Assembly in New York.

Leaders attending the terrorism summit include Canadian Prime Minister Jean Chretien, French President Jacques Chirac and Pakistan President Pervez Musharraf.

Russian President Vladimir Putin and President Bush have been invited, but haven't said if they would attend.

Terrorism experts will present findings, and the world leaders will meet victims from the Bali club bombings, the World Trade Center attacks and Spain's conflict with Basque separatists in an effort to understand the extremism behind worldwide terror, Bondevik said.

While the United Nations has defined terror as the random killing of civilians. Erik Giercksky, an adviser to Bondevik and summit coordinator, said there were many ways of understanding the scourge, but a new definition was not being sought.
