An Islamic State supporter encouraged « lone wolf » attackers to target Prince George and inject poison into supermarket ice creams, a court heard.

Husnain Rashid, 32, of Leonard Street in Nelson, Lancashire provided an « e-toolkit for terrorism » over the internet, the prosecution alleges. He is accused of calling for the prince to be targeted at Thomas’s Battersea primary school in south-west London.

Mr Rashid denies six terrorism offences at Woolwich Crown Court.

The jury was told that the former mosque teacher, who also used to work for a tyre business, ran a « prolific » online channel named the « Lone Mujahid ». He is accused of posting a photograph of the four-year-old prince, along with his school’s address, a silhouette of a jihad fighter and the message: « Even the royal family will not be left alone. » He also allegedly advised a British terrorist in Syria named Omar Ali Hussain on how to make successful attacks, including bringing down « enemy » aircraft with lasers.

The court heard that Mr Hussain was the main person contacted by the defendant who had himself « made preparations » to fight for Islamic State abroad.

Other alleged targets he suggested included a Halloween Parade in New York and railway stations in Australia.

Prosecutor Annabel Darlow said: « His proposals were indiscriminate and made no distinction between adult and child, between members of fighting forces and civilians. « His suggestions included injecting poison into supermarket ice creams and targeting Prince George at his first school. »

Ms Darlow said Mr Rashid specialised in supporting lone attackers with « every conceivable type of attack » including the use of bombs, chemicals and knives.

He is also accused of distributing the al-Qaeda terror magazine Inspire, and allegedly wanted to travel to Syria to fight in Islamic State territories.

The court heard when police raided his house he « hurled » a phone containing a « treasure trove » of evidence over a wall and into an alleyway.

Mr Rashid denies three counts of engaging in conduct in preparation of terrorist acts, one of encouraging terrorism, two of dissemination of a terrorist publication, and one of failing to comply with a notice under the Regulation of Investigatory Powers Act. The allegations span a period between October 2016 and April this year. The trial continues.
