At least 20 schools in Paris have received threats of a terrorist attack. France is in “emergency attack alert”, the maximum alert status of the Vigipirate anti-terrorist plan.

The country has been on maximum alert since Friday's terrorist attack in Moscow. The educational community is threatened and afraid to report it, writes Agnes Poirier, a former headmistress of a French high school who has received death threats on the Internet. In the south of France, dozens of high schools received threats between Monday and Tuesday.
