Security chiefs have confirmed that Jewish schools in the UK were among the seven institutions targeted by a bomb threat shortly after 8am on Monday.
A spokesman for the Community Security Trust tweeted: “After consultation with the Police we advise fully enforce all security procedures.”
There were no devices found and the schools were advised not to evacuate.
The threats are believed to have been hoax telephone calls to the schools themselves. Police in the West Midlands, where two non-Jewish schools received calls, declared the threats “not credible”.
The working theory is that Monday’s calls are part of a pattern of bomb threats that has seen up to 100 schools targeted up and down the country over the past four weeks. It is believed that the calls are being made from abroad and the issue is being handled at a national level.
