Input: In under two minutes, notorious Australian terrorist Khaled Sharrouf managed to fake his way through a Sydney airport check using his brother's passport. On his journey to become an Islamic State Fighter, Sharrouf fled to the Middle East on December 6, 2013 from Sydney airport at 9.11am. Documents obtained by Lateline have shown that although his face was checked twice against the passport photo of his brother, customs officers let him through, the ABC have reported. Although there were 'significant time pressures that day,' national security expert Clarke Jones said the incident was a mistake and the processes may need to be assessed.Australian terrorist Khaled Sharrouf faked his way through airport checkHe fled to the Middle East in 2013 from Sydney airport at 9.11amSharrouf used brother's passport and was allowed through after 2 minutesThis comes after mother of Sharrouf's wife has pleaded for safe passageKaren Nettleton asked Australian Government to help her daughter, TaraReports emerged Tara and her children were trying to return to SydneyTara and her children travelled to Syria to be with her terrorist husband
