Japan’s Shinzo Abe, Former Prime Minister, Is Assassinated

TOKYO—Shinzo Abe, a former Japanese prime minister, died after being shot Friday during an election campaign rally, sending shock waves through a country unaccustomed to gun violence.

Police arrested a 41-year-old man who they said approached Mr. Abe from behind as he gave a speech in the city of Nara and fired twice with what appeared to be an improvised firearm. A doctor who treated Mr. Abe said he had gunshot wounds near the base of his neck and one bullet pierced his heart.
