Islamic State militants have posted what appear to be threats against 4-year-old Prince George online, according to British media.

A photo of the preschool-age prince was discovered on an encrypted instant-messaging app, Telegram.

“Even the royal family will not be left alone,” read the chilling message, the Daily Star reported.

The shot shows the tot standing in front of his pricey South London school, Thomas’s Battersea. It bears the message, “School starts early.”

The encrypted transmission also allegedly included words from a jihadi song which translate as, “When war comes with the melody of bullets, we descend on disbelief, desiring retaliation.”

Cybersecurity expert Barry Spielman told the Daily Star, “This threat to Prince George is chilling.”

“Our intelligence suggests that these threats are to be taken seriously,” he said.

ISIS threatened the queen ahead of the 70th anniversary of the end of World War II in 2015, and just last month Prince Harry was challenged to a fight via video.
