Six steel plates and two coils have been found at a synagogue in Jerusalem, the city’s chief forensic scientist said Thursday.
Police said they were examining the incident, which took place in a public building and is under investigation.
The incident is under the probe of the police and the Shin Bet security service.
The authorities have not yet released a motive.
The city’s director of police, Avraham Avigdor, said he had no information about the location of the artifacts, which were discovered on Thursday morning in the southern part of the Old City.
“We have no information on what led to the discovery, but we have been examining the scene and there are no indications of a crime,” he said.
“I cannot give a specific reason for the finding.
The security of the synagogue is a top priority, so we will not comment on it further.”
Police are asking anyone who may have information about who might have taken the items to contact the Shinbet.
Police have asked the media to avoid mentioning the location in the lead-up to the day’s event, which is expected to be a commemoration of the 10th anniversary of the terror attacks on September 11, 2001.
Security has been stepped up in Jerusalem following the terror attack on a synagogue.
The city has seen several attacks on synagogues and a shooting at a Jerusalem market on Tuesday.
