An ISIS supporter has admitted to encouraging would-be terrorists to target Prince George at his London school. Husnain Rashid called for the 4-year-old to be targeted shortly after the prince—William and Kate’s son and the third in line to the British throne—began to attend Thomas’s school in Battersea, in southwest London, last year. Rashid, 32, posted a photograph of the school superimposed with silhouettes of two masked jihadi fighters, The Guardian reports. He listed the school’s full address and said: “Even the royal family will not be left alone. School starts early.” He initially denied all charges, but admitted Thursday to encouraging terrorism.
