GENEVA - A group of Japanese high school students visiting the U.N. office in Geneva on Tuesday called on the world to reduce the risks associated with military uses of artificial intelligence as the technology becomes integrated into war-making capabilities.

More than 20 "peace messengers" hailing from 19 of Japan's 47 prefectures, including Hiroshima and Nagasaki, came to submit more than 60,000 signatures collected over the past year in an effort toward seeking the abolition of nuclear weapons.
