Japanese former prime minister Shinzo Abe was shot on Friday while campaigning in the city of Nara, a government spokesman said, with public broadcaster NHK saying he appeared to have been shot from behind by a man with a shotgun.
Chief Cabinet Secretary Hirokazu Matsuno said he did not know Abe's condition. Kyodo news agency and NHK said Abe, 67, appeared to be in a state of cardiac arrest when taken to hospital.
NHK, citing the police, said a suspect, Tetsuya Yamagami, 42, had been taken into custody. He was a Nara resident, the report said. Images shared on social media showed a man being tackled after the shooting.
Boris Johnson said on Thursday that he would step down as Britain's prime minister, after a wholesale rebellion of his cabinet, a wave of government resignations and a devastating loss of party support prompted by his handling of the the latest scandal that has engulfed his leadership.
Mr. Johnson said he would stay on in his post until the Conservative Party chooses a new leader, which could take several months. He said he expected the timetable for his departure and the selection of a successor to be decided on Monday by a committee of senior Conservative lawmakers.
"It is clearly now the will of the parliamentary Conservative Party that there should be a new leader," Mr. Johnson said in remarks outside Downing Street. "The process of choosing that new leader should begin now."
