Islamic state has told its members to stop using internet-based communication apps like WhatsApp and Telegram on smartphones, suspecting they are being used by the U.S.-led coalition to track and kill its commanders.
Until recently, the hardline group used such apps to chat with members and supporters outside its main areas of control in Syria, Iraq and Libya — including, say French officials, the assailants who staged attacks across Paris a year ago, killing at least 130 people.
