Paris (CNN) -- Ten suspected Islamists were arrested in fresh raids across France on Wednesday morning as the country widens a clampdown on suspected extremists after a deadly shooting spree last month, the Interior Ministry said.
The raids took place in the cities of Roubaix, Lyon, Valence, Pau, Marseille and Carpentras and in the Lot et Garonne region, the Interior Ministry said.
Meanwhile, 13 alleged radicals arrested Friday were placed under formal investigation for "criminal conspiracy in connection with a terrorist enterprise," and possession and transportation of weapons, officials said.
The formal warning is a point in the French legal system that comes after an arrest and before formal charges are filed.
Nine of the 13 have been jailed, including Forsane Alizza leader Mohamed Achamlane.
The other four were released Tuesday but remain "under judicial control," according to Achamlane's lawyer Philippe Missamou.
On Tuesday, a French prosecutor said the detained radical Muslims were preparing for holy war.
Forsane Alizza and Achamlane were "calling for the establishment of an Islamic caliphate in France and calling for the implementation of Sharia law and inciting Muslims in France to unite for the preparation of a civil war," Paris prosecutor Francois Molins said.
The group was reportedly linked to Mohammed Merah, who was accused of killing seven people in the south of France in March before police killed him after a 32-hour siege of his apartment in the southwestern city of Toulouse. (Read more.)
Wait a minute! You mean to tell me that after France invited Muslims to immigrate to their country, Muslims are now preparing for a war to establish Islam? Where have I heard this before?
