A chilling image has emerged showing an Islamic State (IS) supporter's plot to kill Prince George.
Mosque teacher Husnain Rashid, 32, has admitted a series of terror offences at Woolwich Crown Court.
He posted hundreds of thousands of propaganda messages, including calls for the four-year-old heir to the throne to be attacked while at school.
Last year, Rashid posted a photograph of the prince's school, overlaid with the silhouettes of two masked jihadist fighters, and urged jihadis to take action.
He then sent a message with the school's address, saying: "Even the royal family will not be left alone. School starts early."
Other messages encouraged attacks on British soccer stadiums, Jewish communities and army bases. He also shared instructions on how to make poison and bombs, and called for supporters to inject cyanide into food at grocery stores and poison ice-cream.
"Look around you how many infidels can you reach to and kill, with your car, knife, or even a stone, or poisoning them!" he wrote, according to The Guardian.
"Go out and take revenge! What are you waiting for?... We ask Allah to bless you and make you successful."
Adjourning sentence, Judge Andrew Lees told Rashid: "For the past week I have listened to the most disturbing allegations.
"You have admitted these allegations of encouraging others to commit terrorist activities and publishing statements to encourage the killing of others.
"It is undoubtable that you will receive a lengthy prison sentence and the question of your future dangerousness and the protection of the public is a matter that I will have to give very careful consideration."
