Former Japanese Prime Minister Shinzo Abe has been shot while giving a campaign speech in western Japan.
ABC News partner NHK reported that Abe was bleeding when he collapsed.
Abe's heart is in a "stopped condition," ABC News has learned, and there are no vital signs.
Two shots were heard. The former prime minister was shot in the back and bleeding on-site when he was transported to a hospital.
Authorities have a suspect -- a man in his 40s -- in custody and recovered a weapon at the scene, which is described as a shotgun.
U.S. Ambassador to Japan Rahm Emanuel tweeted late Thursday night, "We are all saddened and shocked by the shooting of former Prime Minister Abe Shinzo."
"Abe-san has been an outstanding leader of Japan and unwavering ally of the U.S.," he said. "The U.S. Government and American people are praying for the well-being of Abe-san, his family, & people of Japan."
