Islamic extremists have directed a death threat at the third in line for the British throne, Prince George.
The Daily Star says terrorist group Islamic State sent a number of threats to the royal family using a confidential messaging app Telegram. The group is claimed to favour Telegram because it encrypts each message, keeping the sender's location concealed.
One of the messages sent included an image of Prince George, accompanied by a chilling caption: "Even the royal family will not be left alone".
A second message said "School starts early", and featured a picture of the young prince outside the south London school he attends, with its name and address in the caption, the Daily Star reports.
The lyrics of a jihadi song had been included alongside one of the messages which roughly translates to "When war comes with a melody of bullets, we descend on disbelief, desiring retaliation".
There have already been questions about the security of Prince George's school, with a video emerging of a woman walking through the school unchallenged just days before he started attending.
Security measures are expected to be increased at the school in response to the threats.
There is no way of tracking the messages sent on Telegram, and internet surveillance firms are now beginning to trawl it more seriously after it emerged as a genuine way for Islamic State affiliates to message one another.
