Japanese former Prime Minister Shinzo Abe was shot on Friday while campaigning for a national election the government said, with public broadcaster NHK saying he appeared to have been shot from behind by a man with a shotgun, Reuters reported.

Police said a 41-year-old man suspected of carrying out the shooting in the western city of Nara had been arrested.

Kyodo news agency and NHK said Abe, 67, appeared to be in a state of cardiac arrest when airlifted to hospital, after having initially been conscious and responsive.

“Such an act of barbarity cannot be tolerated,” Chief Cabinet Secretary Hirokazu Matsuno told reporters, adding that Abe had been shot at about 11:30 a.m. (0230 GMT).

He said he did not know Abe’s condition.

NHK showed video of Abe making a campaign speech outside a train station when two shots rang out, after which the view was briefly obscured and then security officials were seen tackling a man on the ground. A puff of smoke behind Abe could be seen in another video shown in NHK.

A Kyodo photograph showed Abe lying face-up on the street by a guardrail, blood on his white shirt. People were crowded around him, one administering heart massage.

TBS Television reported that Abe had been shot on the left side of his chest and apparently also in the neck.

Political violence is rare in Japan, a country with strict gun regulations. The gun used in the shooting appeared to be home-made firearm, NHK said.

According to Reuters in 2007 Nagasaki Mayor Iccho Itoh was shot and killed by a yakuza gangster. The head of the Japan Socialist Party was assassinated during a speech in 1960 by a right-wing youth with a samurai short sword.

“I thought it was firecrackers at first,” one bystander told NHK.

Police identified the suspected shooter as Tetsuya Yamagami, a resident of Nara.

Abe served two terms as prime minister to become Japan’s longest-serving premier before stepping down in 2020 citing ill health.

But he has remained a dominant presence over the ruling Liberal Democratic Party (LDP), controlling one of its major factions.

His protege, Prime Minister Fumio Kishida, goes into Sunday’s upper house election hoping, analysts say, to emerge from Abe’s shadow and define his premiership.

Kishida suspended his election campaign after Abe’s shooting and was returning to Tokyo where he was due to speak to media at 0530 GMT.

The government said there was no plan to postpone the election.

The ambassador of the United States, Rahm Emanuel, said he was saddened and shocked by the shooting of an outstanding leader and unwavering ally.

“The U.S. government and American people are praying for the well-being of Abe-san, his family, and the people of Japan,” he said in a statement.

Abe is best known for his signature “Abenomics” policy featured bold monetary easing and fiscal spending, read the report.

He also bolstered defence spending after years of declines and expanded the military’s ability to project power abroad.

In a historic shift in 2014, his government reinterpreted the postwar, pacifist constitution to allow troops to fight overseas for the first time since World War Two.

The following year, legislation ended a ban on exercising the right of collective self-defence, or defending a friendly country under attack.

Abe, however, did not achieve his long-held goal of revising the U.S.-drafted constitution by writing the Self-Defense Forces, as Japan’s military in known, into the pacifist Article 9.

He was instrumental in winning the 2020 Olympics for Tokyo, cherishing a wish to preside over the Games, which were postponed by a year to 2021 because of the COVID-19 pandemic, Reuters reported.

Abe first took office in 2006 as Japan’s youngest prime minister since World War Two. After a year plagued by political scandals, voter outrage at lost pension records, and an election drubbing for his ruling party, Abe quit citing ill health.

He became prime minister again in 2012.

Abe hails from a wealthy political family that included a foreign minister father and a grandfather who served as premier, Reuters reported.

First elected to parliament in 1993 after his father’s death, Abe rose to national fame by adopting a tough stance toward unpredictable neighbour North Korea in a feud over Japanese citizens kidnapped by Pyongyang decades ago.

Though Abe also sought to improve ties with China and South Korea, where bitter wartime memories run deep, he riled both neighbours in 2013 by visiting Tokyo’s Yasukuni Shrine, seen by Beijing and Seoul as a symbol of Japan’s past militarism.

In later years in office, Abe refrained from visiting in person and instead sent ritual offerings.
