But his parents still apparently had no idea where he was - with Mr Scurfield , of Barnsley , South Yorkshire , revealing on December 15 : ' I 've heard about the authorities threatening to tell my parents !

' The messages and posts also give an idea of what foreign fighters heading for Syria to fight with the YPG can expect . Mr Scurfield revealed 'quite a lot of Westerners ' pack up and leave after a short time , disappointed by the Kruds ' 'skills and drills ' . But Mr Scurfield was impressed by the attitude of the Kurdish fighters - who are the only troops on the ground fighting . 'The Kurds do n't do stuff like us but they never drip about going on patrol , ' he wrote . Tributes : Fellow-fighters said Mr Scurfield ( pictured ) 'gave his life combating terrorism for his nation ' Warrior : Fellow fighters in Mr Scurfield 's 'Lions of Rojava ' group have posted tributes to him online .
