An attacker beheaded a woman and killed two other people in a church in the city of Nice on Thursday in the second deadly knife attack in France in two weeks.
A man was shot by police and is now in critical condition in a hospital.
France’s chief anti-terrorism prosecutor has said the man suspected of carrying out the Nice attack was a Tunisian born in 1999 who had arrived in Europe on Sept. 20 in Lampedusa, the Italian island off Tunisia.
On Thursday evening a 47-year-old man was taken into custody on suspicion of having been in contact with the perpetrator of the attack, a judicial source said at the time.
On Friday, a 35-year old man, who is a Nice resident, and who is suspected of having met with the assailant the day before the attack, was also taken into custody, a judicial source confirmed.
The third arrest followed immediately afterwards, the police source said.
France has warned its citizens they face a security risk “everywhere” in the world in the wake of the attack inside a church in Nice that left three people dead, Foreign Minister Jean-Yves Le Drian said Friday.
He said France’s highest attack risk warning had been sent to citizens abroad on Thursday evening “wherever they are, because the risk is everywhere.”
