The mother of a British doctor found dead in Syria has told an inquest jury her son didn't tell her he was going to Syria as he knew she would "go crazy and scream."
Fatima Mahmood described the moment her son told her he was going abroad.
She told the court, "He said, Mummy I'm going to Turkey, he said goodbye stood in the doorway."
In November 2012 she discovered the doctor had crossed into Syria and gone missing. Describing her reaction when her daughter told her that he had vanished she said, "My hands were shaking, my mind was blank. I did not start crying straight away. I told my husband I cannot go to my son's funeral at this age."
Mrs Khan went on to tell the court how she travelled to Syria alone "to try and rescue my son."
She added, "I did not feel the Foreign Office was not making enough effort to save my son's life."
