The sentencing of eight English Defence League supporters for violent disorder was temporarily halted after one of them demanded to be updated on the Sydney cafe siege.
Judge Richard Bond briefly adjourned the case after being verbally abused, urged to "pass proper sentences" on Islamic extremists, and asked: "Any news on the Australian hostages?"
Some of the defendants walked around the dock at Birmingham Crown Court during the outbursts, which also included chants of "No surrender to the Taliban".
Judge Bond had already sentenced three of the men when one of them shouted "If there were proper sentences for extremists, the EDL wouldn't be here", and another asked for news of events in Australia.
The judge then left the court-room for several minutes, before returning to continue to address the defendants and explain their sentences.
Among those in the dock over violent scenes at an EDL rally in Birmingham city centre was Otis Bloodworth, who attended the protest event in July 2013 wearing Union Jack boxing gloves and shorts.
CCTV footage played to the court showed Bloodworth, of Drummond Road, Skegness, Lincolnshire, punching a man who was being led away from the event by stewards.
The 35-year-old, who has 43 previous convictions dating back to 1997, was arrested and taken to a police station in March after an appeal for information on the BBC's Crimewatch programme.
When questioned by officers as to whether he had any medical conditions, Bloodworth said he had "Islamophobia" and refused to be represented by a Muslim solicitor.
Bloodworth was jailed for 18 months alongside Benjamin Crowder, who was celebrating his 21st birthday at the protest march.
Crowder, now 22, of Matlock, Derbyshire, was given a two-year sentence after footage was played to the court of him throwing an object at police.
