A college student plotted to kill non-Aryans in a cyanide attack, a court has heard.
Mark Colborne, 36, appeared at Westminster Magistrates' Court in London charged with preparing a terrorist act.
The charge follows an arrest and searches at his home on Butts Road, Sholing, Southampton.
Mr Colborne spoke only to confirm his name, age and address. No indication of plea was given.
Counter-terrorism police searched the house, which Mr Colborne shares with his mother, on 3 June, when he was arrested but later released on bail.
His home was searched again by Hampshire Constabulary and the South East Counter Terrorism Unit on Tuesday, when he was charged with engaging in conduct in preparation of terrorist acts, contrary to section 5(1) of the Terrorism Act 2006.
Mr Colborne is alleged to have possessed chemicals to produce cyanide.
He is also accused of researching techniques and possessing material to help produce lethal poisons and explosives and of expressing intent to kill people of various ethnicities.
He was refused bail and remanded in custody to appear at the Old Bailey on 18 July.
