World leaders delivered messages of shock and support over the shooting of former Japanese Prime Minister Shinzo Abe on Friday.

His death was confirmed several hours after the attack by doctors at the hospital where he had been taken.

Abe, 67, held the title of Japan's longest-serving prime minister and has been a mainstay of politics in the country and on the global level.

Japan's current prime minister, Fumio Kishida, said he was "lost for words."

"I was praying that his life would be saved, but despite that, I came to learn of (his death). It is truly regrettable. I am lost for words. I offer my sincere condolences and prayers that his soul may rest in peace," an emotional Kishida told reporters.

Leaders from around the world expressed their concern over the situation and Abe's condition on the news that he was in hospital.

Germany 'shocked' by shooting

German Chancellor Olaf Scholz said the killing of Abe had left him "stunned and deeply sad." He expressed his condolences for Abe's family, "my colleague Fumio Kishida and our Japanese friends."

"We stand closely by Japan's side even in these difficult hours," he added.

Germany's Foreign Minister Annalena Baerbock said that she was "shocked by the news that Shinzo Abe was shot," before the news of his passing.

"My thoughts are with him and his family," she wrote on Twitter. Baerbock is currently in Bali, Indonesia, for the G20 summit.

European Commission President Ursula von der Leyen called the attack "brutal and cowardly."

Their messages were mirrored in a tweet from NATO chief Jens Stoltenberg. He later said he was "deeply saddened by the heinous killing."

China expresses condolences
