French police have arrested a man suspected of planning an attack on “one or two churches” in a Paris suburb, the country’s interior minister has said.
Sid Ahmed Ghlam, a 24-year-old Algerian national, was detained on Sunday in Paris after he apparently shot himself by accident and called an ambulance.
He is also being questioned over the murder of a woman on Sunday.
France has stepped up security in the wake of recent attacks on the Charlie Hebdo offices and a Jewish supermarket.
Ghlam was known to security services as having expressed a wish to travel to Syria to fight with Islamist militants, French Interior Minister Bernard Cazeneuve said.
When police arrived at the scene on Sunday, they followed a trail of blood to the suspect’s car, where they found weapons and notes on potential targets.
