A man was stabbed to death outside a synagogue in front of his 13-year-old son Wednesday. The two had been studying together in a kollel study hall inside the synagogue before the incident occurred.

The 45-year-old father was treated at the site by emergency responders and then taken to Sheba Medical Center in Tel Hashomer with critical injuries but was later pronounced dead by the medical staff.

The attacker fled the scene, and police are searching the area for the suspect. The Dan Precinct’s crime-fighting unit has been assigned to oversee the investigation.
