«A particularly dangerous and organized network was broken up today,» said French Interior Minister Bernard Cazeneuve, whose government has deployed thousands of soldiers and extra police since the Jan. 7-9 attacks on satirical newspaper Charlie Hebdo and a Jewish supermarket.

Elite police troops, many of them hooded and heavily armed, arrested five people aged 26 to 44 in the raid in Lunel, a small town near France’s Mediterranean coast.

Two of the arrested had returned from Syria, a police source said.

Lunel has attracted intense attention in recent months after local media reported that as many as 10 people from the town, of a population of just 25,000, had sought to travel to Syria to fight alongside jihadists, in particular the Islamic State group. Cazeneuve said on Tuesday those reports were accurate.

In Belgium, where earlier this month police killed two gunmen in one of several raids, three men were arrested in Kortrijk, a town some 10 km (6 miles) from the French border, prosecutors said.
