A French intelligence agent sent a text message by mistake to the mobile phone of a jihadist, inadvertently warning him that he was under surveillance and undermining an investigation, it emerged on Friday. The target of the probe, described as an “Islamist preacher” based in the Paris area, immediately understood that his phone was being tapped and his movements monitored. The incident came as France remains under a state of emergency declared after the 2015 Paris terrorist attacks.
