This evening's terrorist stabbing attack in Petah Tikvah injured one person - but it could have been a lot deadlier were it not for the courageous actions of Renaddi Kasau, who helped tackle the knife-wielding attacker without any thought for his own safety.

Speaking to Arutz Sheva, Kasau recounted how the victim of the stabbing - a 25-year-old haredi man - had been sitting next to him at a bus stop outside the city's mall, when a man came running towards them with a knife drawn, screaming "Allahu Akbar!"

"The terrorist came from right over there, from the bridge next to the (bus) station. He started running towards here. I was sitting on the bench next to the bus stop and the guy who was (later) stabbed was also sitting next to me and shouted "It's a terrorist! A terrorist!

"And then the terrorist continued running towards here shouting 'Allahu Akbar! Allahu Akbar!'"

After first running away from the attacker, Kasau turned around and pursued him - as he plunged his knife into his victim.

"I started to run after him and he turned around and stabbed the guy who was with me over there," he said. "The people here from the mall helped us to catch him."

The brave have-a-go-hero then went back to help tend to the injured victim, who was evacuated to nearby Beilinson hospital with light wounds.

Despite the terrifying circumstances, Kasau said wasn't afraid.

"We didn't feel fear."
