"Wallah (I swear to God) theres no good left in u if none of u do something about the australian newspaper mocking our prophet pbuh. Dont be cowards. Wheres the honour whrres the courage. Let the heads fly and blood flow," he wrote on his social media page, according to the Daily Telegraph.
The 23-year old ethnic Bangladeshi fled Australia unexpectedly, just "months away from finishing an RMIT building management course," the media outlet points out. Some time later, he appeared in social media photos posing with weapons alongside Sydney-born extremist Mohamed Elomar. Other photos the young extremist shared contain shocking images of dead bodies. "Rahman's Facebook page and Twitter accounts are littered with photos too graphic to be published," the Daily Telegraph stresses.
"Everything was OK, then suddenly he just left the country. It is very upsetting but it was nothing in our control and we have discussed many times with federal police. It is a matter of shame that we have been put in this position and this type of offence," Suhan's father Lutfur Rahman told the Herald Sun.
However, the young Australian decided to trade his life for "martyrdom" in "Sham." Suhan posted several messages praising the attack on Charlie Hebdo and the Kouachi brothers, calling them "martyrs."
"May allah accept the french brothers who terrorised france. Allahu akbar. Day by day we will bring the war home to you," he wrote.
"They say were all charlie. I say that means uze all deserve death and worse. I say stuf the peaceful protests. Spill blood young aussies. Dont be humiliated especially if u cant b here in sham," the extremist claimed, calling upon young Australian Muslims.
