French police on Tuesday arrested 29 people in a sting operation targeting a network of terror financing for jihadists in Syria, prosecutors said. The network, active since 2019, mostly operated via the purchase of crypto-currency coupons whose references were given to jihadist contacts in Syria and then credited to bitcoin accounts, the anti-terror prosecutors' office said in a statement. This way to transfer funds marks a departure from previous methods identified by France's anti-terror financing and money laundering services, which mostly involved cash mandates, it said. "Constant surveillance of these networks prompted terrorist organisations to seek more opacity by using crypto-currencies such as bitcoin," the statement said. edy-gd/jh/js/mbx
