France has seized the passports of six of its citizens who it says were planning to travel to Syria to join Islamist groups fighting in that country's civil war. It's the first time the French government has used a measure that was approved in November to limit the number of French citizens joining Islamist groups in the Middle East.

The BBC quoted Interior Minister Bernard Cazeneuve as saying the six people wanted to join the self-described Islamic State. An unnamed source quoted by Agence France-Presse said they were planning to go to Syria imminently. Their passports and ID cards have been confiscated for six months, the news agency said. The order can be renewed after that period. They can appeal the order in court, the BBC added.

French Prime Minister Manuel Valls said last month that more than 1,000 people in the country have joined — or were planning to join — Islamist groups in Iraq and Syria.

Today's development follows last month's deadly attack in Paris on Charlie Hebdomagazine and a Jewish supermarket. Those attacks were carried out by French citizens who claimed allegiance to Islamist groups.
