Australian authorities are providing assistance to a man detained in Lebanon over allegations he tried to plant a bomb on an Etihad flight out of Sydney.
Dual citizen Amer Khayat reportedly broke down in tears as he faced a Lebanese military court in Beirut on Monday when insisting he wasn't a terrorist.
"I am a nightclub man, a drugs man," he told the court in Arabic according to News Corp Australia.
"I didn't know anything."
Khayat's matter was adjourned to July 30.
It's been alleged Khayat attempted to smuggle an improvised explosive device onto an Abu Dhabi-bound flight in July 2017 but his luggage was rejected at a Sydney Airport check-in counter because it was too heavy.
The Australian foreign affairs department on Tuesday confirmed it was providing consular assistance to an Australian man detained in Lebanon.
That help may include visits to prison to monitor his welfare, providing a list of local lawyers and help communicating with family or contacts.
Two of Khayat's Sydney-based brothers, Khaled, 49, from Lakemba and Mahmoud, 32, of Punchbowl, have been charged in Australia and are each facing two counts of preparing or planning a terrorist act.
They remain in custody in Sydney.
Another brother, Tareq Khayat, an Islamic State commander and Lebanese citizen, was detained in Iraq earlier this year, according to media reports in April.
The federal government is currently seeking new powers for Australian Federal Police to check people's identities at Australian airports without reason and order them to leave.
