A yeshiva student who shot the Jerusalem terrorist says he was busy studying when suddenly shots rang out, prompting him to grab his gun and eventually kill the Palestinian attacker

“We realized something happened so I cocked my handgun,” Yitzhak Dadon told Ynet Thursday evening.

“I went up on the roof and waited for the terrorist. Meanwhile, I saw blood and shattered glass,” Dadon said. “The terrorist continue firing in the air, so I waited to see him again, and then I shot him twice in the head.”

Dadon says the terrorist continued firing even after he was hurt.

“He kept on firing until an IDF officer arrived and shot him again,” Dadon said.

The gunman infiltrated a rabbinical seminary at the entrance of Jerusalem and opened fire after nightfall Thursday, police said. The ZAKA emergency response service has confirmed at least eight people have been killed.

Paramedics said they treated several people for injuries – among them four in serious to critical condition.
