LONDON: Three far-right extremists were convicted in a UK court on Wednesday of planning terrorist attacks against mosques and synagogues.

The men were part of an online neo-Nazi group that had stockpiled more than 200 weapons and were close to finishing a 3-D printed semi-automatic gun.

Brogan Stewart, 25, Marco Pitzettu, 25, and Christopher Ringrose, 34, were found guilty of multiple terrorism and firearms offenses, following a nine-week trial at Sheffield Crown Court. They will be sentenced in July.

The group were arrested in February last year after an investigation by counter terrorism police found that the men were intent on carrying out a violent attack.

“These extremists were plotting violent acts of terrorism against synagogues, mosques and Islamic education centers,” said Bethan David, head of the Crown Prosecution Service’s Counter Terrorism Division. “By their own admission, they were inspired by SS (Nazi) tactics and supremacist ideology.”

Counter terrorism police said that the men belonged to an online group that provided an echo chamber of extreme right-wing views. They shared horrific racial slurs, glorified mass murderers and encouraged violence.

The group, which idolized the Nazi Germany regime, prepared for what they claimed would be a “race war” by sourcing body armor and weapons including machetes, hunting knives, swords and crossbows.

“They were a group that espoused vile racist views and advocated for violence, all to support their extreme right-wing mindset,” said Detective Chief Superintendent James Dunkerley, head of Counter Terrorism Policing North East. “All three took real-world steps to plan and prepare for carrying out an attack on innocent citizens.”
