Shinzo Abe assassin used homemade gun

This is the clunky homemade weapon used to assassinate former Japanese leader Shinzo Abe Friday in a country that has some of the strictest gun laws in the world.

Pictures from the shocking attack appear to show the killer — identified as 41-year-old military veteran Tetsuya Yamagami — tossing the crude, black tape-covered firearm moments after gunning down the ex-prime minister.

It remained near the assassin’s feet as security tackled him to the ground — while others started doomed attempts to save Abe, 67, who bled to death from two deep gunshot wounds, including one in the neck.

The images show what appears to be a rudimentary double-barrelled shotgun, with two tubes taped together atop a wooden body and a black handle.

Military officials told public broadcaster NHK that Yamagami had been in the Maritime Self-Defense Force for three years — from 2002 to 2005 — and was “frustrated” with Abe.

Police found several possible explosives during a raid on Yamagami’s home, and the suspect confessed that he had “manufactured multiple pistols and explosives so far,” NHK said.

The shooting was particularly shocking in a country that prides itself on having some of the strictest gun laws in the world.

Private citizens are barred from owning handguns, and licensed hunters may own only rifles — and even then only after attending classes, passing a written test and undergoing a mental health evaluation and background check.

Shootings, when they occur, typically involve “yakuza” gangsters using illegal weapons. When mass killings do take place in Japan, as when 19 people were murdered at a facility for mentally disabled people in 2016, they tend to be carried out with knives.
