A 43-year-old man was severely wounded in a Yavneh supermarket on Wednesday morning, and police suspect the attack may have been nationalistically motivated.
Yavneh is a city in central Israel.
Magen David Adom EMTs and paramedics administered medical treatment and transferred the victim to Kaplan Hospital in Rehovot.
Israel Police caught the stabber.
"When I arrived at the scene they showed me inside," MDA paramedic Itzik Yom Tov said. "I saw a man in his 40s laying conscious on the floor, with stab wounds on his upper body. We administered lifesaving medical treatment, bandaged his wounds and stopped the bleeding. We transferred the victim to Kaplan Hospital in severe condition."
"The terrorist is a 19-year-old Arab youth who arrived at the supermarket and stabbed a 42-year-old man, severely injuring him," an Israel Police spokesman said. "The suspect was arrested by civilians and police officers who arrived at the scene."
"The stabber lives in Judea and Samaria, and he is currently being interrogated. We are investigating the incident."
