The network of agile and semiautonomous cells shows the reach of the extremist group in Europe even as it loses ground in Syria and Iraq, AP reports.
The officials, including European and Iraqi intelligence officials and a French lawmaker who follows the jihadi networks, described camps in Syria, Iraq and possibly the former Soviet bloc where attackers are trained to target the West. Before being killed in a police raid, the ringleader of the November 13 Paris attacks claimed he had entered Europe in a multinational group of 90 fighters, who scattered "more or less everywhere."
Fighters in the units are trained in battleground strategies, explosives, surveillance techniques and counter surveillance, the security official said.
Several security officials have said there is growing evidence to suggest the bulk of the training is taking place in Syria, Libya and elsewhere in North Africa.
The question for many intelligence and security officials is now turning to just how many more fighters have been trained and are ready for more attacks.
A senior Iraqi intelligence official who was not authorized to speak publicly said people from the cell that carried out the Paris attacks are scattered across Germany, Britain, Italy, Denmark and Sweden. Recently, a new group crossed in from Turkey, the official said.
