This week the Jewish Museums in both London and Sydney were targeted with hoax bomb threats, prompting evacuations and police searches.

London’s Jewish Museum, located in Camden, was evacuated on Monday after a bomb threat was made around lunchtime.

Around 100 people, including visiting schoolchildren and staff, were asked to leave “as a precaution,” as police closed off roads and searched the building. Nothing was found.

In a statement, the Museum said there were two groups of schoolchildren in at the time, adding: “We were able to evacuate the building quickly and safely. We would like to thank our staff and visitors for their patience and cooperation.”

Last month, the Museum’s chief executive Abigail Morris said the institution had increased the number of security guards it employs following the terrorist attack on the Jewish Museum in Brussels in 2014.

The Sydney Jewish Museum was evacuated following a bomb threat received by its staff on Tuesday.

Staff at the neighbouring building, which houses the New South Wales Jewish Board of Deputies, Jewish Communal Appeal and United Israel Appeal also were evacuated.

Police and security officials searched the buildings and allowed staff to reenter two-and-a-half hours later.

These bomb threats come on the heals of a series of bomb threats in the United States. More than 90 Jewish schools and centres have been targeted since January. There were also a number of British Jewish schools and centres targeted in January.
