A French member of Islamic State has admitted that the organisation had made plans to send child soldiers disguised as underage asylum seekers to Europe to carry out terrorist attacks.

French jihadist Jonathan Geffroy was captured by the Free Syrian Army in early 2017 and given over to French authorities later that year where currently he awaits trial for criminal conspiracy, Le Monde reports.

Geffroy was interrogated several times between September 2017 and February 2018 by the French General Directorate of Internal Security (DGSI), claiming that he wanted to cooperate with the counter-terrorism organisation.

The jihadist said that he was in close contact with Jean-Michel and Fabien Clain while in Syria. The brothers are believed to be the highest-ranking French members of Islamic State still alive in the region and they were the ones, according to Geffroy, who wanted to send child soldiers to Europe to carry out attacks.

“Have you attended conversations about preparations for attacks or external operations?” an investigator is said to have asked Geggroy, who responded: “I know that future external operations will be committed by children who grew up in the area and who, after adolescence, will be sent to the West.”

Child soldiers are not a new concept for Islamic State. As far back as 2015, the group bragged about using child soldiers labelled “Cubs of the Caliphate” and featured them in videos, showing the child soldiers executing alleged spies. The group has also used child soldiers in the Philippines, according to a report from last year.

The smuggling of migrants has also become a major revenue stream for the terror group, according to Italian intelligence chief Alessandro Pansa who said last year: “Its biggest sources of income — smuggling oil products and antiquities, are at the edge of drying out. We think terrorists are resorting to human trafficking as a new source of revenue.”
