Six prestigious schools in central Paris and 14 schools in Britain were evacuated on Tuesday following hoax bomb threats.
Six prestigious schools in central Paris and 14 schools in Britain were evacuated on Tuesday following hoax bomb threats.
The Paris schools received practically identical calls between 10:20 am (0920 GMT) and 11:20am, French police said.
Students at Charlemagne, Fenelon, Montaigne, Condorcet, Henri IV and Louis le Grand schools, all in up-market districts of the French capital, were moved to secure areas while police carried out searches.
The alerts were lifted for all six schools by the end of the afternoon.
In Britain, four London schools also received calls.
Six schools in the Birmingham area in central England and four in Cornwall, southwest England, reported similar incidents.
"Four schools across London this morning all reported receiving calls claiming suspicious devices had been left in their premises," a Scotland Yard spokesman told AFP.
"They were evacuated as a precaution. The premises were searched. Once those were completed the incidents were stood down and they are being treated as malicious communications."
A Devon and Cornwall Police spokeswoman told AFP that four secondary schools in Cornish towns "received calls suggesting a potential security threat".
All four were evacuated but by 9:00am (0900 GMT), "there was quickly found to be no threat and no risk to any children or staff. Enquiries are continuing into the matter".
West Midlands Police Assistant Chief Constable Carl Foulkes said: "Police intelligence suggests there is no credible threat behind the calls.
"They mirror the hoaxes several schools received just a few days ago.
"Local police officers have been sent to the affected schools to carry our checks and to offer reassurance.
"A police investigation is under way to find the person responsible."
