Shinzo Abe, former Japan PM, shot during campaign speech

Japan's former prime minister Shinzo Abe has been taken to hospital bleeding after collapsing while delivering a speech in the city of Nara in western Japan, public broadcaster NHK reported on Friday.
Here is what we know so far:
*According to local media reports, Abe is showing no vital signs after attack
*A sound like a gunshot was heard at the time, and a male suspect was detained at the scene, NHK said.
*An NHK reporter on the scene said they could hear two consecutive bangs during Abe's speech.
*According to reports, Abe was shot from behind.
* Abe was holding his chest when he collapsed, with his shirt smeared with blood
*Abe was making an election campaign speech ahead of Sunday’s election for the parliament's upper house
* Japan has some of the world's toughest gun-control laws, and annual deaths from firearms in the country of 125 million people are regularly in single figures. Getting a gun licence is a long and complicated process even for Japanese citizens, who must first get a recommendation from a shooting association and then undergo strict police checks.
