The Tunisian man who killed three people in a French church only recently arrived in Europe, officials say, writes BBC.
The suspect, 21, had an Italian Red Cross document, issued after he arrived on the Italian island of Lampedusa by migrant boat last month.
He was shot by police and is in a critical condition. One of the victims was “virtually beheaded”, said the French chief anti-terrorism prosecutor.
President Emmanuel Macron said it was an “Islamist terrorist attack”.
He said the number of soldiers being deployed to protect public places - such as churches and schools - would rise from 3,000 to 7,000. Anti-terror prosecutors have opened an investigation, and France has raised its national security alert to the highest level.
