NARA, Japan – Former Prime Minister Shinzo Abe, one of Japan’s most influential postwar leaders, died Friday at the age of 67 after being shot while delivering a stump speech in the western city of Nara two days ahead of a national election.

Japan’s longest-serving leader was shot by a 41-year-old man who approached him from behind at around 11:30 a.m. as he was speaking in front of Kintetsu Railway’s Yamato-Saidaiji Station, police said, adding he collapsed on the ground after two shots were heard. He was rushed to a hospital with blood seen on his shirt.

A doctor with the Nara Medical University Hospital later said at a press conference that Abe was pronounced dead at 5:03 p.m. and the wound was deep enough to reach his heart, adding the cause of death is believed to be blood loss.

Tetsuya Yamagami, a resident of Nara, was arrested at the scene on suspicion of attempted murder, the police said. The suspect was formerly a member of the Maritime Self-Defense Force, apparently for about three years through 2005, according to government sources.

“It’s not a grudge against the political beliefs of former Prime Minister Abe,” the Nara prefectural police quoted Yamagami, whose recent occupation remains unknown, as saying. His home was later searched by the police, who found an item that could be an explosive, they said.

A Kyodo News reporter at the scene saw the attacker silently approach Abe, who had been speaking for several minutes, before shooting him.

Louds screams were heard from the crowd and Abe fell to the ground seconds later. Yamagami was immediately apprehended by police officers.

A campaign staff member was seen desperately trying to revive Abe by pushing on his chest with both hands as he lay on the ground with his eyes closed. People nearby called for medical assistance.
