A couple from Tel Aviv in their 50s, were among those killed at the Brussels Jewish Museum on Saturday.
As they weren’t carrying identification on them at the time, it took time to identify them.
The third victim was a female museum volunteer.
The fourth victim, was not killed and still hospitalized and seriously wounded, is a 23 year old museum employee.
The Belgium police no longer have any suspects in custody. The person they initially arrested is now considered a witness.
Police believe the shooter was driven to the museum by an accomplice in an Audi car.
