Another young Australian man who travelled to Syria to fight in the civil war has been killed.

Caner Temel, 22, was recruited to fight against the Assad regime allegedly for Al Qaeda and its affiliate Jabhat al-Nusra.

Temel is from Auburn in Sydney's west and is of Turkish descent.

His death comes just days after the killing of Sydney couple Yusuf and Amira Ali near Aleppo last weekend.

Early reports suggested that the couple was in Syria for humanitarian reasons but it has since been revealed Ali was allegedly fighting for Jabh at al Nusra.

Both Temel and Ali were allegedly aided by Sydney man Hamdi Al Qudsi to travel to Syria.

Court documents filed late last year state Temel (aka Abu Moussa) was in Syria with the intent to "engage in hostile activity".

In December, Al Qudsi was arrested and charged with assisting people to travel to Syria to fight in the long-running conflict.

He faces seven charges under the Crimes Act relating to foreign incursions and recruitments and faces a maximum of 10 years in jail.

Between June and August last year, Al Qudsi is accused of helping Temel travel to the region to engage in "armed hostilities".

The Australian Federal Police say Al Qudsi has links to the banned terrorist organisation Jabhat al-Nusra Front, which is affiliated to Al Qaeda.

Friends of Temel have taken to Facebook to express sorrow at his death saying he has been martyred in Syria, with one post lamenting his death in Arabic saying "May God have mercy on his soul".

Family and friends are being called together for a memorial service this evening.
