French school where teacher fatally stabbed evacuated over bomb alert

French authorities say a high school where a teacher was fatally stabbed last week has been evacuated over a bomb alert, as France’s President cut short travel plans abroad to host a security meeting.
The prefecture of the northern Pas-de-Calais region said the decision was made to evacuate the Gambetta-Carnot high school in Arras after police received a bomb threat via its website.
