One of three men found guilty of terrorism charges for torching a Melbourne mosque in the name of Islamic State has lashed out in a fiery court outburst, calling police "dogs" and the jury who convicted him "nobodies".

In the Supreme Court on Thursday, Abdullah Chaarani, 28, Ahmed Mohamed, 26, and Hatim Moukhaiber, 30, were found guilty of engaging in a terrorist act for their roles in burning down the Imam Ali Islamic Centre in Fawkner on December 11, 2016.

Chaarani and Mohamed were also found guilty of a single charge each of attempting to engage in a terrorist attack, over an unsuccessful attempt to destroy the mosque 16 days earlier.

Moments after the jury delivered its verdicts, Moukhaiber’s mother started calling out to the jury, and then her son yelled out to anti-terrorism police.
