Speaking to 7NEWS Australia, the teenager's cousin Sam said he and his family were only two weeks into their holiday when tragedy struck, and that a funeral for the teen was arranged in Lebanon. She said: "When his father heard the news, he flew from Sydney to Lebanon to see him.

So far, police have arrested the owner of the paragliding company, which operated out of nearby Jounieh, as they continue to search for the missing instructor.

As Hussein's family deals with the devastation in Lebanon, friends have paid tribute to the teen, with one person posting online saying he "wanted to feel the adrenaline of flying".

They wrote: "(He) went to Lebanon for a holiday — full of dreams, excitement, and the energy of youth. Like many young men, he wanted to feel the adrenaline of flying, so he went hang gliding off the mountain peaks of Lebanon. What was meant to be a moment of thrill became his final moment.

"May Allah grant his family patience and reunite them with him in the highest levels of Jannah. And as for us — still breathing, still planning, still distracted — take this as a wake-up call. The only promise in life is death."

A spokesperson for the Austrailian Department of Foreign Affairs and Trade confirmed the office is offering consular assistance to the family of an Australian who died in Lebanon. They sais: "We send our deepest condolences to their family at this difficult time,' a spokesperson said.
